NAME

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

AUTHOR

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::CiscoVTP
SNMP::Info::CDP
SNMP::Info::CiscoStats
SNMP::Info::CiscoConfig
SNMP::Info::Layer2

Required MIBs

CISCO-C2900-MIB

Part of the v2 MIBs from Cisco.

Inherited MIBs

See "Required MIBs" in SNMP::Info::CiscoVTP for its MIB requirements.

See "Required MIBs" in SNMP::Info::CDP for its MIB requirements.

See "Required MIBs" in SNMP::Info::CiscoStats for its MIB requirements.

See "Required MIBs" in SNMP::Info::CiscoConfig for its MIB requirements.

See "Required MIBs" in SNMP::Info::Layer2 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.

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-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)

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);
