Description: The number of ingress check failures on this ECT VID. This is referred to as the ingress check, and this counter increments whenever a packet is discarded for this VID because it has not come from an interface which is on the shortest path to its SA or because it is not upstream for the individual DA if relaxed ingress checking is applied.

What is ieee8021SpbEctDynamicEntryIngressCheckDiscards?

This counter records the number of frames discarded on an Equal-Cost Tree (ECT) Virtual LAN because they failed the ingress check on a Shortest Path Bridging (SPB) network. Frames fail the ingress check if they arrive on an interface that is not on the shortest path to their source address, indicating a possible loop or misconfiguration. Network administrators monitor this counter to detect topology problems and to ensure that SPB multicast distribution is working correctly.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.26.1.5.1.6
snmpwalk -v2c -c public <target> IEEE8021-SPB-MIB::ieee8021SpbEctDynamicEntryIngressCheckDiscards

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.26.1.5.1.6.1
snmpget -v2c -c public <target> IEEE8021-SPB-MIB::ieee8021SpbEctDynamicEntryIngressCheckDiscards.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ieee8021SpbEctDynamicEntryIngressCheckDiscards.1
