SYNOPSIS

# Let SNMP::Info determine the correct subclass for you.
my $c2900 = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
# These arguments are passed directly to SNMP::Session
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $c2900->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION

Provides abstraction to the configuration information obtainable from a C2900 device through SNMP.

For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

 my $c2900 = new SNMP::Info::Layer2::C2900(...);

Inherited Classes

SNMP::Info::Layer2::Cisco

Required MIBs

CISCO-C2900-MIB

Part of the v2 MIBs from Cisco.

Inherited MIBs

See ``Required MIBs'' in SNMP::Info::Layer2::Cisco for its MIB requirements.

GLOBALS

These are methods that return scalar value from SNMP

Overrides

$c2900->vendor()

Returns 'cisco' :)

$c2900->cisco_comm_indexing()

Returns 1. Use vlan indexing.

Globals imported from SNMP::Info::Layer2::Cisco

See ``GLOBALS'' in SNMP::Info::Layer2::Cisco for details.

TABLE METHODS

These are methods that return tables of information in the form of a reference to a hash.

Overrides

$c2900->interfaces()

Returns reference to the map between IID and physical Port.

On the 2900 devices i_name isn't reliable, so we override to just the description.

Next all dots are changed for forward slashes so that the physical port name is the same as the broad-casted CDP port name.
    (Ethernet0.1 -> Ethernet0/1)

Also, any weird characters are removed, as I saw a few pop up.

$c2900->i_duplex()

Returns reference to map of IIDs to current link duplex

Crosses $c2900->c2900_p_index() with $c2900->c2900_p_duplex()

$c2900->i_duplex_admin()

Returns reference to hash of IIDs to admin duplex setting

Crosses $c2900->c2900_p_index() with $c2900->c2900_p_duplex_admin()

$c2900->i_speed_admin()

Returns reference to hash of IIDs to admin speed setting.

C2900-MIB Port Entry Table

$c2900->c2900_p_index()

Maps the Switch Port Table to the IID

("c2900PortIfIndex")

$c2900->c2900_p_duplex()

Gives Port Duplex Info

("c2900PortDuplexStatus")

$c2900->c2900_p_duplex_admin()

Gives admin setting for Duplex Info

("c2900PortDuplexState")

$c2900->c2900_p_speed_admin()

Gives Admin speed of port

("c2900PortAdminSpeed")

See ``TABLE METHODS'' in SNMP::Info::Layer2::Cisco for details.

SET METHODS

These are methods that provide SNMP set functionality for overridden methods or provide a simpler interface to complex set operations. See ``SETTING DATA VIA SNMP'' in SNMP::Info for general information on set operations.

$c2900->set_i_speed_admin(speed, ifIndex)

Sets port speed, must be supplied with speed and port "ifIndex"

Speed choices are 'auto', '10', '100'

Crosses $c2900->c2900_p_index() with $c2900->c2900_p_speed_admin() to utilize port "ifIndex".

    Example:
    my %if_map = reverse %{$c2900->interfaces()};
    $c2900->set_i_speed_admin('auto', $if_map{'FastEthernet0/1'}) 
        or die "Couldn't change port speed. ",$c2900->error(1);

$c2900->set_i_duplex_admin(duplex, ifIndex)

Sets port duplex, must be supplied with duplex and port "ifIndex"

Speed choices are 'auto', 'half', 'full'

Crosses $c2900->c2900_p_index() with $c2900->c2900_p_duplex_admin() to utilize port "ifIndex".

    Example:
    my %if_map = reverse %{$c2900->interfaces()};
    $c2900->set_i_duplex_admin('auto', $if_map{'FastEthernet0/1'}) 
        or die "Couldn't change port duplex. ",$c2900->error(1);
