NAME¶
SNMP::Info::Layer2::Catalyst - SNMP Interface to Cisco Catalyst devices running
Catalyst OS.
AUTHOR¶

SYNOPSIS¶
# Let SNMP::Info determine the correct subclass for you.
my $cat = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $cat->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
DESCRIPTION¶
SNMP::Info subclass to provide information for Cisco Catalyst series switches
running CatOS.
This class includes the Catalyst 2920, 4000, 5000, 6000 (hybrid mode) families.
This subclass is not for all devices that have the name Catalyst. Note that some
Catalyst switches run IOS, like the 2900 and 3550 families. Cisco Catalyst
1900 switches use their own MIB and have a separate subclass. Use the method
above to have SNMP::Info determine the appropriate subclass before using this
class directly.
See
SNMP::Info::device_type() for specifics.
Note: Some older Catalyst switches will only talk SNMP version 1. Some newer
ones will not return all their data if connected via Version 1.
For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above.
my $cat = new SNMP::Info::Layer2::Catalyst(...);
Inherited Classes¶
- SNMP::Info::Layer2::Cisco
- SNMP::Info::CiscoStack
Required MIBs¶
- Inherited Classes' MIBs
- See "Required MIBs" in SNMP::Info::Layer2::Cisco for its own MIB
requirements.
See "Required MIBs" in SNMP::Info::CiscoStack for its own MIB
requirements.
These MIBs are found in the standard v2 MIBs from Cisco.
GLOBALS¶
These are methods that return scalar value from SNMP
- $cat->os()
- Returns 'catalyst'
- $cat->os_ver()
- Tries to use the value from SNMP::Info::CiscoStats->os_ver() and
if it fails it grabs $cat-> m_swver()->{1} and uses
that.
- $cat->vendor()
- Returns 'cisco'
- $cat->cisco_comm_indexing()
- Returns 1. Use vlan indexing.
Global Methods imported from SNMP::Info::Layer2::Cisco¶
See documentation in "GLOBALS" in SNMP::Info::Layer2::Cisco for
details.
Global Methods imported from SNMP::Info::CiscoStack¶
See documentation in "GLOBALS" in SNMP::Info::CiscoStack for details.
TABLE METHODS¶
These are methods that return tables of information in the form of a reference
to a hash.
Overrides¶
- $cat->interfaces()
- Returns the map between SNMP Interface Identifier (iid) and physical port
name.
- $cat->i_name()
- Returns reference to hash of iid to human set name.
"portName"
- $cat->i_physical()
- Returns a map to IID for ports that are physical ports, not vlans,
etc.
- $cat->bp_index()
- Returns reference to hash of bridge port table entries map back to
interface identifier (iid)
Crosses ("portCrossIndex") to ("portIfIndex") since some
devices seem to have problems with BRIDGE-MIB
