l2tHistoryWindowSize

Module: L2TV1-MIB

OID (symbolic): L2TV1-MIB::l2tHistoryWindowSize

OID (numeric): 1.3.6.1.4.1.2.6.119.4.7.1.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The window size of the L2T Tunnel History Table (l2tHistTunnelTable) and the L2T Session History Table (l2tHistSessTable).

When retrieved by an SNMP GET or GET-NEXT request, this number specifies the maximum number of entries which will be maintained in each of these tables.

When modified by an SNMP SET request, the device will set the value of this object as close as possible to the requested value based on implementation and available resources.

What is l2tHistoryWindowSize?

Read-write window size limiting how many entries the Tunnel History and Session History tables (l2tHistTunnelTable, l2tHistSessTable) will retain; setting it requests a new size, but the device applies the closest value it can support given its resources.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.6.119.4.7.1.1.9
snmpwalk -v2c -c public <target> L2TV1-MIB::l2tHistoryWindowSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2.6.119.4.7.1.1.9.1
snmpget -v2c -c public <target> L2TV1-MIB::l2tHistoryWindowSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.2.6.119.4.7.1.1.9.1 i <value>
