Configuring Node Aliases
The node alias feature enables administrators to determine the MAC address and location of a
given end ‐ station (or node) using the node’s Layer 3 alias information (IP address) as a key. With
this method, it is possible to determine that, for instance, IP address 123.145.2.23 is located on
switch 5 port 3.
The passive accumulation of a network ʹ s node/alias information is accomplished by “snooping”
on the contents of network traffic as it passes through the switch fabric.
In the C3, node data is automatically accumulated into the ct ‐ alias mib, and by default this feature
is enabled. The NetSight Console Compass utility and Automated Security Manager (ASM) use
the information in the node/alias MIB table.
It ʹ s important to make sure that inter ‐ switch links are not learning node/alias information, as it
would slow down searches by the NetSight Compass and ASM tools and give inaccurate results.
Purpose
To review, disable, and re ‐ enable node (port) alias functionality on the switch.
