SYNOPSIS

scli [options] [hostname] [community]

DESCRIPTION

scli provides a simple command line interface on top of the Simple Network Management Protocol (SNMP). It can be used to read data from devices and to configure them with simple commands. It relies on the capabilities of the devices and thus not all commands may work with all devices.

The optional hostname argument is the name or the IP address of the remote host. scli talks to this host's SNMP agent on the default port number 161 using the SNMP over UDP transport mapping.

The optional community argument is the community string used to communicate with the remote SNMP agent. The default string is public. Please check the configuration of the SNMP agent to get a clue about the community string to use, if the default community string does not work.

OPTIONS

scli accepts the following options:

-V, --version

Show version of program.

-c, --command

Process the given commands and exit.

-d seconds, --delay=seconds

Set delay between screen updates in seconds. The default delay between updates is 5 seconds.

-f, --file

Process commands from a file and exit.

-h, --help

Show summary of scli options.

-i, --inet

Execute in inet mode. This option implies -q, -n and -x.

-n, --norc

Do not evaluate ~/.sclirc on startup.

-q, --quiet

This flag causes scli to supress some informational messages.

-s, --dry-run

Parse scli commands but do not actually execute them. This allows to perform syntax checking on scli scripts.

-x, --xml

Generate XML output instead of the default output which is optimized for humans and more difficult to parse by programs.

COMMAND OVERVIEW

scli is a simple command interpreter. scli commands are organized in a hierarchy. This section only describes the top-level commands. Invoke the help command described below to get a complete list of all commands supported by scli.

open

Establish an association to a remote SNMP agent.

close

Close the association to a remote SNMP agent.

exit

Exit the scli command interpreter.

help

Display help information about the scli command interpreter including a full list of the scli command hierarchy.

history

Show the history of the last scli commands.

create

Create new object instances on the remote SNMP agent. This command has many sub-commands which are used to instantiate very different things.

delete

Delete object instances from the remote SNMP agent. This command has many sub-commands which are used to delete very different things.

run

Execute a specific action. This command has many sub-commands which are used run very different actions.

set

Modify object instances on the remote SNMP agent by assigning new values. This command has many sub-commands which are used to set very different things.

show

Show information provided by the remote SNMP agent. This command has many sub-commands focusing on various aspects of the system.

monitor

Monitor information provided by the remote SNMP agent. This command has many sub-commands focusing on various aspects of the system. scli monitors provide a live display of network and device activities. Information is shown in a compact human readable format and updated in regular intervals. The initial update interval length is determined by the delay command line option.

dump

Dump scli command sequences to restore the configuration of the remote SNMP agent.

scli supports recursive command evaluation. When a command is entered which is not a leaf of the command tree, then the interpreter will recursively invoke all commands in the subtree identified by the entered command. In particular, entering show will cause scli to retrieve and display all information accessible from the remote SNMP agent. 100 scli version 0.4.0 (c) 2001-2010 Juergen Schoenwaelder

3COM MODE

The 3com scli mode allows to manipulate virtual lans (vlans) on 3com bridges. It is based on the PRODUCTMIB which is implemented at least on 3Com SuperStack II switches.

create 3com bridge vlan <vlanid> <name>

delete 3com bridge vlan <regexp>

set 3com bridge vlan name <vlanid> <name>

set 3com bridge vlan ports <regexp> <ports>

dump 3com bridge vlan

The create 3com bridge vlan command is used to create a new virtual LAN with the given <vlanid> and <name>.

The delete 3com bridge vlan command deletes all selected virtual LANs. The regular expression <regexp> is matched against the virtual LAN names to select the vlans that should be deleted.

The set 3com bridge vlan name command changes the name of a virtual LAN.

The set 3com bridge vlan ports command allows to assign ports to port-based virtual LANs. The regular expression <regexp> is matched against the virtual LAN names to select the vlans that should be modified. The <ports> argument contains a comma separated list of port numbers or port number ranges, e.g. 1,5,7-8.

The show 3com bridge vlan info command shows summary information about all selected virtual LANs. The optional regular expression <regexp> is matched against the virtual LAN names to select the virtual LANs of interest. The command generates a table with the following columns:

RS232 MODE

The rs232 scli mode is based on the RS-232-MIB as published in RFC 1659.

show rs232 details

The show rs232 details command describes the selected RS 232 interfaces in detail.

SCLI MODE

The scli mode provides commands that can be used to display and manipulate the internal state of the scli interpreter.

open <nodename> [<community>]

close

run scli walk <oid> [<oid> ...]

run scli scan <network> [community]

run scli sleep <secs>

create scli plugin <module>

delete scli plugin <module>

exit

help

history

create scli alias <name> <value>

delete scli alias <regexp>

create scli interp <name>

delete scli interp <regexp>

set scli regex [<regexp>]

set scli debugging [<regexp>]

set scli pager <pager>

set scli retries <retries>

set scli timeout <milliseconds>

set scli format <fmt>

set scli mode <mode>

show scli info

show scli command info [<regex>]

show scli command details [<regex>]

show scli command tree

show scli aliases

show scli modes [<regex>]

show scli schema [<regex>]

show scli alarm info

The open command establishes an association to a remote SNMP agent. The <nodename> argument is the DNS name or the IP address of the remote node. Scli will try to talk to the SNMP agent on this node by using the default port number (usually 161) and the default transport mapping (usually SNMP over UDP). The optional <community> argument is the community string needed to communicate with the remote SNMP agent. The default community string is "public". Opening an association while an association is already established is not considered an error. The existing established association will be closed automatically before an attempt to create a new association is started.

The close command closes an established association to a remote SNMP agent. Invoking the close command when no association is established is not considered an error and will do just nothing.

The run scli walk command is a debugging utility which simply performs a MIB walk. Note that scli does not have general MIB knowledge and hence the output requires some post-processing.

The run scli scan command is a utility which scans an IPv4 address space identified by the <network> argument. The <network> must be specified in the format <ipv4address>/<prefix>. The optional <community> argument is the community string needed to communicate with the remote SNMP agent. The default community string is "public".

The run scli sleep command simply sleeps for the given amount of seconds.

The create scli plugin command dynamically loads an scli mode into a running scli process. This can be used to dynamically extend scli with modules coming from other sources. Dynamic loadable modules also simplify the development and management of site-specific modules.

The delete scli plugin command removes a previously loaded modules from a running scli process.

The exit command terminates the scli interpreter. An end of file in the standard input stream will also terminate the the scli interpreter.

The help command displays some help information including a list of all top-level scli commands.

The history command displays the scli command history list with line numbers.

The create scli alias command creates the alias <name> for the scli command (fragment) <value>. If the alias <name> already exists, then the new <value> will be assigned to the existing alias.

The delete scli alias command removes previously defined aliases from the scli interpreter. The regular expression <regexp> is matched against all alias names in order to select the aliases that are deleted.

The create scli interp command creates a new internal scli interpreter with the name <name>.

The delete scli interp command deletes previously defined scli interpreters from the main scli interpreter. The regular expression <regexp> is matched against all alias names in order to select the interpreter(s) to be removed.

The set scli regex command controls how scli matches regular expressions. The optional regular expression <regexp> is matched against the regular expression options. A successful match turns a regular expression option on while an unsuccessful match turns a regular expression option off. Invoking the command without the <regexp> argument will turn all regular expression options off. The currently defined regular expression options are "extended" for POSIX extended regular expressions and "case-insensitive" for case insensitive matches.

The set scli debugging command sets the debugging level of the SNMP engine. The optional regular expression <regexp> is matched against the debugging levels. A successful match turns a debugging level on while an unsuccessful match turns a debugging level off. Invoking the command without the <regexp> argument will turn all debugging levels off. The currently defined debugging levels are "session" for the SNMP session layer, "request" for the SNMP request handling layer, "transport" for the SNMP transport layer, "packet" for the SNMP packet layer, and "asn1" for the ASN.1 coding layer.

The set scli pager command defines the shell command which is used as a pager if the output produced by an scli command does not fit on a single screen. The output is passed to the <pager> shell command via its standard input stream.

The set scli retries command defines the number of SNMP request retries before giving up requesting a certain object.

The set scli timeout command defines the number milliseconds between subsequent SNMP request retries.

The set scli format command defines the output format used by subsequent scli commands. The currently supported formats are "scli" and "xml". The "scli" format is the default output format and described in this documentation. The "xml" output format is experimental and therefore not described here.

The set scli mode command defines the scli mode used by subsequent scli commands. Setting the mode to "protocol" will force scli to work in protocol mode. Setting the mode to "normal" causes scli to work in normal mode where certain status messages are suppressed.

The show scli info command displays the current status of the scli interpreter.

The show scli command info command displays summary information about scli commands. The optional regular expression <regex> is matched against the command names to select the scli commands.

The show scli command details command displays detailed information about scli commands. The optional regular expression <regex> is matched against the command names to select the scli commands.

The show scli command tree command displays the scli command tree. The full command syntax is displayed for each leaf node.

The show scli aliases command lists all scli command aliases. The first column in the generated table lists the aliase names while the second column shows the alias values.

The show scli modes command shows information about the scli modes. An scli mode is a logical grouping of related commands (e.g., all commands that deal with printers). The optional regular expression <regex> can be use to select a subset of the available scli modes.

The show scli schema command produces xml schema definitions for the selected scli modes. An scli mode is a logical grouping of related commands (e.g., all commands that deal with printers). The optional regular expression <regex> can be use to select a subset of the available scli modes.

The show scli alarm info command displays summary information about all known alarms.

SNMP MODE

The snmp scli mode is based on the SNMPv2-MIB as published in RFC 1907, the SNMP-FRAMEWORK-MIB as published in RFC 3411, the SNMP-USER-BASED-SM-MIB as published in RFC 3414, the SNMP-VIEW-BASED-ACM-MIB as published in RFC 3415, the SNMP-TARGET-MIB as published in RFC 3413, the SNMP-NOTIFICATION-MIB as published in RFC 3413, and theNOTIFICATION-LOG-MIB as published in RFC 3014.

TCP MODE

The scli tcp mode is based on the TCP-MIB as published in RFC 2012. It provides commands to browse information specific to the TCP transport protocol.

show tcp info

show tcp listener

show tcp connections

show tcp states

monitor tcp connections

monitor tcp states

The show tcp info command displays parameters of the TCP protocol engine.

The show tcp listener command displays the listening TCP endpoints. The command generates a table with the following columns:

  LOCAL  local TCP endpoint
  STATE  transmission control block state (listen)

The show tcp connections command displays the connected TCP endpoints including the current state of the connection as seen by the remote SNMP agent. The command generates a table with the following columns:

  LOCAL  local  TCP endpoint
  REMOTE remote TCP endpoint
  STATE  transmission control block state

The transmission control block state is either closed, synSent, synReceived, established, finWait1, finWait2, closeWait, lastAck, closing, or timeWait.

The show tcp states command displays the distribution of TCP transmission control block states together with a list of known port names in each state. The command generates a table with the following columns:

  COUNT number of transmission control blocks per state
  STATE transmission control block state
  PORTS well-known ports associated with the state

The command uses some heuristics to identify the interesting port numbers. First, all local port numbers are considered where the local port number matches one of the listening port numbers. From the remaining connections, all local port numbers are considered with a well known name. From the remaining connections, all remote port numbers are considered with a well known name. All remaining connections are aggregated under the pseudo name - (hyphen). Unspecified port numbers are show using the pseudo name * (star).

The monitor tcp connections command displays the connected TCP endpoints including the current state of the connection as seen by the remote SNMP agent. The information is updated periodically.

The monitor tcp states command displays the distribution of TCP connection states. The information is updated periodically.

UDP MODE

The scli sflow mode is based on the SFLOW-MIB as published in RFC 3176 and the SFLOW5-MIB published on the slow.org web site. It provides commands to browse information specific to sflow probes.

show sflow info

show sflow receiver

The show sflow info command displays information about an sflow implementation.

The show sflow receiver command displays information about sflow receivers.

UDP MODE

The scli udp mode is based on the UDP-MIB as published in RFC 2013. It provides commands to browse information specific to the UDP transport protocol.

show udp listener

show udp stats

The show udp listener command displays the listening UDP endpoints.

The show udp statistics about datagrams received or sent.

INTERACTIVE MONITOR COMMANDS

Several single-key commands are recognized while scli is running in monitor mode:

space

Update the display.

^L

Redraw the screen.

h or ?

Print a help page.

c

Toggle display of contact summary information.

d

Set the delay in seconds between updates.

m

Toggle display of mode specific summary information.

n

Toggle display of network layer summary information.

q

Quit the monitoring mode.

x

Exit scli immediately.

t

Toggle display of transport layer summary information.

w

Freeze the screen until someone hits a key.

UNITS

scli displays numbers in a compact format. It uses several abbreviations to explain the units of the numbers. Here are some explanations:

bps

Bits per second.

fps

Frames per second.

pps

Packets per second.

sps

Segments per second.

Large numbers are usually displayed with a scaling factor (k=10^3, m=10^6, g=10^9, t=10^12, p=10^15, K=2^10, M=2^20, G=2^30, T=2^40m, P=2^50).

ALIASES

Long command names can be abbreviated by using aliases. The scli interpreter maintains a list of aliases. Every command is first checked whether the first word matches an alias. If the first word matches an alias, then the first word will be replaced by the value of the alias. Alias expansion only happens once.

Aliases are not expanded when the scli interpreter is running in non-interactive mode.

REGULAR EXPRESSIONS

scli generally uses POSIX.2 Extended Regular Expressions. The regular expression matching is case sensitive.

READLINE

scli supports the GNU readline library. The GNU readline library provides command line editing as well as command completion capabilities. Please consult the GNU readline documentation for a detailed description of the readline features.

HISTORY

scli supports the GNU history library. The GNU history library provides a history expansion feature that is similar to the history expansion provided by 'csh'. Please consult the GNU history library documentation for a detailed description of the history features.

PAGER

scli respects the PAGER environment variable when running interactively. If the PAGER environment variable exists and the output generated by an scli command does not fit on the terminal, then the output is written to the standard input of the PAGER.

FILES

~/.scli_history

The history of scli commands.

~/.sclirc

The scli startup file.

~/.inputrc

Individual readline initialization file.
