Thx for that tip, Levi . Didn't know the two commands could be in conflict. So I got rid of "access vlan" on a test switchport 0/32 and show interface status seems to indicate that swx 0/32 is back to default--access port for default VLAN 1. It's not a trunk port. But "voice vlan" seems to allow the phone to tag/encapsulate its traffic VLAN 7 anyway. It's like a hybrid access port that allows 802.1Q for media endpoints only. Is that a good way to describe it?
I will get rid of "access vlan" for the remaining phone ports today (need a maintenance window as it causes our endpoints to reinitialize), and I'll reply again with the status of the 1238's CPU load and the bcmLINK.0 task...
CJ:
I branched the topic of voice VLANs to a new question.
The switchport voice vlan <vlan id> [ cos <value> ] [dscp <value>] command is used for a couple specific scenarios:
1) it sets the access port to also accept tagged traffic with the specified VLAN ID
2) if the phone supports LLDP-MED, the phone should automatically switch to the specified VLAN for its traffic, as well as use the specified DSCP/COS values (CoS (5); and DSCP (46) are default for this command)
For example, if not doing LLDP-MED, then these configurations are pretty much the same thing:
interface switchport 0/1
switchport access vlan 100
switchport voice vlan 200
interface switchport 0/1
switchport mode trunk
switchport trunk allowed vlan 100,200
switchport trunk native vlan 100
I hope this makes sense, but please do not hesitate to reply to this discussion with further questions or additional information about "voice vlans." I will be happy to help.
