cannot specify multiple ports in mac-address-table static command

[mhousley]

Hello, i have a 6513 switch with a SUP720 supervisor module running v6.2.18 SXF11 and have a Microsoft NLB problem requiring a Static MAC address configuration to fix the problem..

I have tried to apply the command: -

mac-address-table static 02bf.0a30.011e vlan 20 interface gi12/11 gi12/12 po1

But the command errors at the "g" on the second interface definition.

Adding the command 3 times, each with a single interface doesn't work either, as each one overwrites the previous one.

i have done this in the past on other software versions and it has worked, but i cannot find out why this now doesn't work - am i doing something wrong?

Hi

I think it's because cisco doesn't support static unicast arp entry:s pointing to more than one port. Try with multicast mac-address instead.

Here are a good link that explains this.
