NAME

SNMP::Info::Layer2::C2900 - SNMP Interface to Cisco Catalyst 2900 Switches running IOS

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 "Cant 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)

    Table Methods imported from SNMP::Info::Layer2::Cisco

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, $if_map{FastEthernet0/1})
        or die "Couldnt change port speed. ",$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, $if_map{FastEthernet0/1})
        or die "Couldnt change port duplex. ",$c2900->error(1);
