islVlanControlEnable
Module: ISLVLAN-MIB
OID (symbolic): ISLVLAN-MIB::islVlanControlEnable
OID (numeric): 1.3.6.1.4.1.11.2.4.9.1.1.1.5
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Indicate the behavior for processing ISL VLAN packets.
A value of disabled(1) means that no per-VLAN monitoring happens on this interface.
A value of explicitlyOnly(2) means that only VLANs that correspond to an islVlanEntry that was explicitly created by a management application. If the probe sees an ISL packet that doesn't correspond to an explicitly created islVlanEntry, the probe will not process the packet in any per-VLAN tables.
A value of implicitCreate(3) means that a new islVlanEntry is automatically created when a ISL packet is seen with an unknown VLAN ID.
What is islVlanControlEnable?
This read-write value controls how the interface processes ISL VLAN packets: not at all (disabled), only for explicitly created VLAN entries (explicitOnly), or by auto-creating entries for unknown VLANs seen on the wire (implicitCreate). An admin picks implicitCreate for automatic VLAN discovery on a monitoring probe, or explicitOnly when only specific, pre-approved VLANs should be tracked. For example, setting this object to implicitCreate(3) means the probe automatically creates a new VLAN table entry the first time it sees an ISL frame tagged with a previously-unseen VLAN ID.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11.2.4.9.1.1.1.5 snmpwalk -v2c -c public <target> ISLVLAN-MIB::islVlanControlEnable
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11.2.4.9.1.1.1.5.1 snmpget -v2c -c public <target> ISLVLAN-MIB::islVlanControlEnable.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.11.2.4.9.1.1.1.5.1 i <value>
