Just started to investigate a medium/large network setup where it seems all of the LWAPs are connected to switchports configured as trunks and all of the LWAPs are in local mode. Each switchport is configured like this...
description Access Point Port
switchport trunk native vlan 20
switchport mode trunk
srr-queue bandwidth share 10 10 60 20
mls qos trust cos
macro description cisco-wireless
auto qos voip trust
spanning-tree bpduguard enable
Trunking on the switchport is shown below, potentially a lot of frames getting sent to the APs that will not be processed because of the capwap tunnels
Port Mode Encapsulation Status Native vlan
Gi2/0/25 on 802.1q trunking 20
Port Vlans allowed on trunk
Port Vlans allowed and active in management domain
Port Vlans in spanning tree forwarding state and not pruned
Given this is a pretty busy network, there are configurations on each of these ports that may not be needed, and each AP is going to drop tagged frames, is it worth going around and fixing each of these ports? There are about 100 of them. The wireless infrastructure works, seems to perform okay, but wondering if I can increase performance/reliability by getting a better port config on each of these. Is that cisco-wireless macro typically used for APs supporting voice?
What is the best practice switchport configuration for an AP in local mode supporting voice/Qos?
- Performance hit or not, is you are using LWAPP/CAPWAP just use an access port for the AP (but in the correct Vlan where CAPWAP is operating in).
Should have mentioned that of all of those APs, only two are in FlexConnect mode. Kinda looks like someone just blindly copied the port config to all of the AP ports.
- Which is unwanted (indeed). performance penalties include unneeded trunk traffic to the CAPWAP-based AP's (e.g.).
