Etherchannel on your ISR

September 30th, 2008 • Related • Filed Under

Well it took a while but finally in 12.4(17.6), Etherchannel support has been introduced for the embedded FE/GB interfaces on the 2811, 2821, 2851, 3825 & 3845. This feature has been supported on the NM-1GE, HWIC-1GE-SFP, HWIC-1FE & HWIC-2FE modules residing in an ISR since 12.3(8)T, but now we are finally able to configure/enable the feature on the onboard interfaces as well. Please see the following document for further details: Etherchannel on ISR

    I did a test just three months ago on an ISR running 12.4(15)T4 Adv IP and EtherChannel didn’t seem to work on that T train IOS. When I reverted back to IOS 12.4(19) then the feature worked. The document you mentioned did not specifically say it would work on the 12.4 T train so I wonder if it is fully supported yet?

    Thanks,

    William

    Nope it’s not available on T train IOS yet. I’m told you will see it rolled into 12.4(next release)T but we’ll have to wait an see :-)

    Hi William, you will need to discuss 12.5M with your local Cisco SE.

    A few days back, got my hands on an ASR 1006, I was trying to integrate into the existing setup. I found out that it did not support VLANs.. Is it so?

    Vineet,

    The ASR’s support of VLAN’s is different from say the ISR’s support for VLAN’s but the ASR does support VLAN’s. Further information and sample configurations can be found here:

    In the second link, please substitute ASR where you see MCP listed.
