|
||||
|
||||
SNMP::Info::Layer2::C2900 - SNMP Interface to Cisco Catalyst 2900 Network Switches
|
||||
|
||||
=head1 DESCRIPTION
|
||||
|
||||
Provides abstraction to the configuration information obtainable from a
|
||||
C2900 device through SNMP.
|
||||
|
||||
MIBS: CISCO-C2900-MIB
|
||||
|
||||
Inherits all SNMP::Info::Layer2 methods.

die "Couldn't connect.\n" unless defined $c2900;
|

|

|

Sets or returns the SNMP::Session object

|
||||
|
||||
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 broadcasted CDP port name.
|
||||
(Ethernet0.1 -> Ethernet0/1)
|
||||
|
||||
Also, any weird characters are removed, as I saw a few pop up.
|

=item $c2900->i_duplex()
|

Returns reference to map of IIDs to current link duplex

Returns reference to hash of IIDs to admin duplex setting
