NIC Teaming with two GbE2c switches in C3000

[Lmm_1 · Accepted solution]

You need to tagg those ports and put them on both VLAN´s, basically make it work as 802.1q port... it might be something like this for each port on trunk 1:

>> Main# /cfg/port XX
>> Port XX# tag e


>> /cfg/l2/vlan XX
>> VLAN XX# add XX(Port)

then apply and save, with this config port 17 and 18 will be able to talk on VLAN 1 and 10.

Thank you very much. Applying tagging to VLAN's on ports 17 & 18 fixed the problem. I could then add the ports to both VLAN's.

I have set both the iSCSI and LAN Teams to TLB with fault tolerance. I have left the TLB method as Automatic. Is that what you would recommend?

Thank you very much for your replies and also thank you to the other respondents.

In this case (Teaming embedded with mezz on a c3k), the best option will be TLB.

Thank you again. A couple of final questions if I can. Should I Port-Fast enable the teamed ports connected to the iSCSI VLAN as well as the LAN VLAN?

I also have 2 blades running VMware ESX 3.5 with a similar setup i.e. teaming one embedded and on mezzanine port together. This may be outside your area of expertise, but should I apply Port-Fast enabled to those ports as well?

You should aply portfast to any port connected to a host in order to avoid STP delays (Listening, learning...etc)... OS doesnt make any difference, if you got different vlans on a vswitch, the port where the VMNIC goes ,must be tagged.

Thank you. I am now comfortable with the way my system operates after following your suggestions.
