Most of the reference material I have seen on cisco.com has RT video being marked DSCP 34 and mapped to a CBWFQ. However, part of the Enterprise MediaNet QoS Design document refers to TelePresence traffic being in the strict priority queue which should be limited to 33% max of lin bandwidth. Being in the LLQ makes sense to me but everything else I see has it as lower priority. Are these documents contradictory or is it me? If it's not me, what works best in practice? ... View more

I am reasonably certain that in a redundant Catalyst 4510R-E with dual Sup V, all 4 GBIC ports are active and available. Correct?                  ... View more

I have an unusual request to support an access point with a single external antenna to cover a small physical area (elevator car!!). All Cisco's currently shipping APs have dual band antennas using MIMO for throughput in "normal" deployments. Will a deployment with a single antenna work?                   ... View more

If I'm linking branch network sites - with no servers/ applications - over an unsecure network I would likely run site to site IPSec tunnels to provide encryption. If I wanted ALL traffic to be encrypted, I could force all users in the branches to sit behind an ASA and force connections via AnyConnect clients and I would have end to end encryption. What value would using MACsec as an alternative provide? Would traffic be encrypted between the last switch and the WAN router? Thanks ... View more

I know that PVLAN is not supported on a FEX when the parent switch is a Nexus 7000, but does anyone know if the equivalent functionality can be provided using VLAN ACLs or Port ACLs - assuming the Promiscuous port device is directly connected to an F2e module on the 7K? Thanks ... View more

Is there any reason why I shouldn't use the same ASA box to terminate AnyConnect VPN sessions and also act as a Phone Proxy? Thx                  ... View more

If I buy a migration from WCS to Prime using the part code below, is it possible to install it as a new deployment or will i have to use a migration tool?

I know that the deployment guide for 2600/3600 access points states that if you have surveyed for a 3600 deployment, you don't need to survey again for a 2600 deployment. As the the 3600 is the higher specification model, is it safe to assume the reverse? I.e. a site survey carried out using 2600 access points is valid for a 3600 deployment, or is this too simplistic?           ... View more

If I'm upgrading dual redundant power supplies in a Catalyst 4507 from 1000W (data) to 1400W (data), can it be done without taking the switch through a power cycle? I'm guessing no as I read that the switch will not recognize a 1400W PSU in bay 2 if there is still an original 1000W PSU in bay 1..                  ... View more
