Cisco 3750 Catalyst Switches for Microsoft Network Load Balancing

[Murali Gadde]

I am trying to enable NLB on Cisco 3750 IOS ver 12.1(11). I got the following error and not sure if ver 12.1 supports this future or not.?

Config -

arp 172.16.63.241 0300.5e11.1111

mac-address-table static 0300.5e11.1111 vlan 200 interface fa1/0/1 fa1/0/4
below is the error that got for the above
Hulc platform supports single port static addresses only
Number of ports that were tried to configure : 2

Please let me know if anyone have any suggestions?

Thanks.

What are you trying to accomplish here. Are you doing something virtual that would need this static entry.

Trying to added static ARP in Cisco 3750 for server virtual MAC and add static mac-address of virtual to two switch ports.

I am getting an error with the below step

mac-address-table static 0300.5e11.1111 vlan 200 interface fastEthernet 1/0/1 fastEthernet 1/0/4

Hulc platform supports single port static addresses only

Number of ports that were tried to configure : 2

We trying to do Microsoft NLB and the config help that used is in the below URL

We have a similiar setup like you are trying to do here our ios ver is 122-52.SE. We had a different issue because it involved our Pix but we had to get with TAC and since then we have not had any issues. But the configuration is correct. I going to try it on a test switch and see what I get back.

Just tested on Cisco 3750 IOS ver 12.2(25) and it worked. Means

its IOS issue.

Thanks.

Not sure if this was a typo. But if this a gig switch 3750 is should look like this. Correct me if I'm wrong

mac-address-table static 0300.5e11.1111 vlan 200 interface gig1/0/1 gig1/0/4
