How to select a port as active port?

Chen needed clarification on some Virtual Connect items:



Hi Experts,


Could you help us to confirm the query?


About the selecting rule for Active/Standby Port described below, I want to confirm some questions.


1. what is "TOE tag"?

2. how to confirm "TOE tag"?

3. in the uplink ports of a VC module, that is, uplink ports under one MAC address,

   how to select a port as active port?


HP Virtual Connect for the Cisco Network Administrator <>



Q2: Can I manually choose which port channel is the preferred channel for a vNet?

A2: No, VC does not currently support setting the ‘port role’ for vNets (or Shared Uplink Sets)

  with LACP enabled (connect mode ‘auto’). VC determines which port channel is active and

  which is standby, based on the following criteria,

  1 - Number of functional uplinks per port channel,

  2 ? Total bandwidth provided by each port channel,

  3 ? if the previous two are a tie, then the VC module with the lowest MAC address (see TOE tag)

  will provide the active port channel. With the information above, the Administrator could construct

  the primary port channel with one addition uplink in order to make it the preferred port channel.



Vincent came to our aid:


The toe tag is the label on the VC module in 2 parts, one stuck on the upper side of the module, the other hanging out and detachable, with the factory-set Administrator password and the MAC address of the module used in the determination below. It's called toe tag after the tags attached to the big toe (foot finger) of dead bodies for identification in morgues, I've always thought the metaphor was kind of weird...

For the uplinks of a single module, VC will by default attempt to aggregate them with LACP which would make them all Active. If you don't want to use LACP, you can set Connection Mode to Failover on the vNet and then choose which uplink is active.



Looks like "TOE" tags gets us into the morgue not to the TCP Offload Engine that I was thinking of. Hope this helps. Let us know if you have other questions.
