16

The 2800 SW will always generate cold boot and port link up traps (if connected) while booting; this behaviour 
is fixed through using the SNMP MIB group mgmt:snmp:snmp-Traps:TrapsInfo (in RFC1213-MIB). Link-
down/up traps will be sent when a port is disconnected and connected, respectively. 
 
 

Polling 

 
Depending on facilities offered by the SNMP manager, a number of variables can be read out and in a few cases 
be edited and set. Many 2800 SW variables are contained in the ‘system’ and ‘interfaces’ sections of RFC1213-
MIB. Others are found in RFC1493 (bridge MIB), RFC1493 (Ethernet), and RFC1757 (RMON MOB). 
The examples and drawing are taken from the Castle Rock SNMPc manager.
