...."then we query the switch using snmp immediately upon getting the linkup notification (linkup will give us port number only) to get the rest of the information (i.e. mac address on port and the current VLAN id)...."

How do you do this by SNMP?  My 2950s don't store the mac address table in any sort of SNMP readable place...unless theres an IOS mod to do it?  

Thanks!
Alex

Sorry folks, saw this discussion just now... So, missed the fun. 

Yes, we use mac-notification primarily with most Cisco switches.
Primary reason is that we get the port#, MAC Address, and port VLAN in
one shot - i.e. the Cisco MAC-Notification trap which the switch sends
us.  If for some reason, we have to use the snmp linkup notification
(due to the absence of mac-notification or if there is some problem with
the mac-notification), then we query the switch using snmp immediately
upon getting the linkup notification (linkup will give us port number
only) to get the rest of the information (i.e. mac address on port and
the current VLAN id).

The answer is always in the release notes.  :-)  (Looks like you were
right on Ryan)

http://www.cisco.com/en/US/products/ps6128/prod_release_note09186a008053
a3ed.html#wp140796

When the Cisco Catalyst Express 500 Series (CE500) is added to the Clean
Access Manager as a managed switch, it will use linkup/linkdown SNMP
trap notification by default. With release 3.6(2) and above, the CE500
can be configured to use mac-notification traps using the Advanced
configuration page for the switch (under Switch Management > Devices >
List > Config [Switch IP] > Config > Advanced). Note that the switch
ports of the CE500 must be assigned to the OTHER role (not Desktop or IP
phone) on the switch's Smartports configuration, otherwise,
mac-notification will not be sent out. See also Supported Switches for
Cisco Clean Access Out-of-Band (OOB).
