| 
 | |
| SNMP::Info::Layer2::C1900 - SNMP Interface to old C1900 Network Switches
 | |
| 
 | |
| =head1 DESCRIPTION
 | |
| 
 | |
| Provides abstraction to the configuration information obtainable from a 
 | |
| C1900 device through SNMP. See inherited classes' documentation for 
 | |
| inherited methods.
 | |
| 
 | |
| Inherits from:
 | |
| 
 | |
|  SNMP::Info::Layer2
 | |
| 
 | |
| Required MIBs:
 | |
| 
 | |
|  STAND-ALONE-ETHERNET-SWITCH-MIB (ESSWITCH-MIB)
 | |
|  MIBs listed in SNMP::Info::Layer2
 | |
| 
 | |
| ESSWITCH-MIB is included in the Version 1 MIBS from Cisco.
 | |
| They can be found at ftp://ftp.cisco.com/pub/mibs/v1/v1.tar.gz
