rlIgmpMldSnoopVlanOperHostTimeOut

Module: CISCOSB-rlBrgMulticast-MIB

OID (symbolic): CISCOSB-rlBrgMulticast-MIB::rlIgmpMldSnoopVlanOperHostTimeOut

OID (numeric): 1.3.6.1.4.1.9.6.1.101.55.5.5.1.21

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: The amount of time that should pass before aging out an entry in the rlIgmpSnoopMembershipTable for this vlan. DEFVAL { rlIgmpMldSnoopVlanOperRobustness * rlIgmpMldSnoopVlanOperQueryInterval + rlIgmpMldSnoopVlanOperQueryMaxResponseTime }

What is rlIgmpMldSnoopVlanOperHostTimeOut?

This read-only value reports the actual, currently effective host aging timeout in milliseconds for this VLAN's combined membership table, typically computed from the Robustness Variable, Query Interval, and Max Response Time. An administrator checks this operational value to know exactly how long a host's membership entry survives without a refresh under the current timer settings, rather than calculating it by hand. For example, if the Robustness or Query Interval values are changed, rlIgmpMldSnoopVlanOperHostTimeOut reflects the new resulting aging timeout automatically.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.6.1.101.55.5.5.1.21
snmpwalk -v2c -c public <target> CISCOSB-rlBrgMulticast-MIB::rlIgmpMldSnoopVlanOperHostTimeOut

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.6.1.101.55.5.5.1.21.1
snmpget -v2c -c public <target> CISCOSB-rlBrgMulticast-MIB::rlIgmpMldSnoopVlanOperHostTimeOut.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> rlIgmpMldSnoopVlanOperHostTimeOut.1
