Hey guys
In a single Cisco 4507 chassis with redundant Sup7-E supervisors
According to the link below, if you run in redundant mode, only the first 2 uplinks (out of 4) on each supervisor may be used.

I'm having a hard time clarifying: does this mean that all 4 ports are passing traffic? Does anyone know whether you can form a port-channel between say port 1 sup1 + port 1 sup2?
Or does this mean that port 1 sup1 is active and port1 sup2 is a standby (like a firewall HA). With ports 3 and 4 being unusable.
Haven't played with the traditional big campus switches for awhile!
the redundant supervisors, at least for the Sup720 in a 6500, are not active/active. they are passing state table information to each other in case of failure but standby is not processing packets. may be the same for the 7E in the 4507.
If you checkout the links it just says active on both supervisors for the 7E....
I think what you are asking is the interfaces on the sup cards are active? The way I read it, you can use the first two interfaces on both sup cards. The last two on each are shutoff. So you could do a port channel with Te5/1, Te5/2, Te6/1, Te6/2, but you could not use /3 or /4 interfaces on either card. See figure two here - http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-4500-series-switches/data_sheet_c78-612364.html
This would make sense as you don't want all your uplinks on a single sup that then fails.

yeah that's what I think i.e. I can use the first 2 ports on both supervisors, even the redundant supervisor, all act as 'active' ports.
Obviously if i lose a sup then its ports fails.
