cardIPTableSize
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::cardIPTableSize
OID (numeric): 1.3.6.1.4.1.277.1.7.2.1.137
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The maximum number of IP routing table entries supported by the card. If set to 0, routing table size is assumed unlimited.
What is cardIPTableSize?
This sets a cap on how many IP routing table entries this card is allowed to hold, with a value of 0 meaning no cap is enforced. An admin lowering this from 0 (unlimited) to a specific number is deliberately protecting the card's memory from being exhausted by an unexpectedly large routing table, at the cost of the card discarding routes past that limit if the network ever needs more than the configured cap. For example, an admin sets cardIPTableSize to 5000 on a card with limited memory to guard against a route-leak elsewhere in the network from exhausting that card's memory, accepting that only the first 5000 routes will be kept.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.7.2.1.137 snmpwalk -v2c -c public <target> CASCADE-MIB::cardIPTableSize
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.7.2.1.137.1 snmpget -v2c -c public <target> CASCADE-MIB::cardIPTableSize.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.7.2.1.137.1 i <value>
