6509 MAC behaviour
Hi,
Why would I have a different port for a same MAC-address on a different linecard?
For example this MAC is going to Te2/5 on all linecards except Linecard 7 that is going to Te7/5.
sh mac add add 0014.4fcb.b15a
Legend: * - primary entry
age - seconds since last seen
n/a - not available
S - secure entry
R - router's gateway mac address entry
D - Duplicate mac address entry
Displaying entries from DFC linecard [2]:
vlan mac address type learn age ports
----+----+

+
+

* 126 0014.4fcb.b15a dynamic Yes 0 Te2/5
Displaying entries from active supervisor:

126 0014.4fcb.b15a dynamic Yes 35 Te2/5
Displaying entries from standby supervisor:

Edit:*I should also mention there is no static MAC configured on any of these switches. Only dynamic MAC's are learned.
Are you doing some sort of NIC teaming on the server?
Ok, I don't know alot about the NIC teaming software however, i have run into a lot of problems with it in the past.
What software is it? Who is the manufacturer?
Thats the NIC Teaming software on the server right?
