Node Alias is a feature that you can use to discover information about end systems on a per-port basis. As a packet from the end system transits through a Node Alias-enabled port, its key attributes are captured in a database that can be queried (CTRON Alias MIB). Enabling Node Alias on ports of interest provides a powerful troubleshooting tool for network administrators.
Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X870, X440-G2, X620 series switches.
Currently, 100 packets per second per slot are admitted for snooping. Packets are dropped if the rate exceeds 100 pps.

In Extreme Access Control (NAC/Mobile IAM), node and alias information may not be visible after enabling the Node Alias feature in ExtremeXOS. Associated show commands in ExtremeXOS are not impacted.
This issue can occur when Node Alias is enabled for the first time after Access Control has already discovered the switch and determined its capabilities. This issue may also occur when you upgrade to ExtremeXOS 22.2.1 after Access Control has already determined if the switch supports the MIB.
