VLAN Management
Voice VLAN
Cisco Small Business 300 Series Managed Switch Administration Guide
•
Assign ports as candidates to the Voice VLAN. (This is configured by using
the process described in the
section.)
•
Assign the QoS mode per port to one of the following:
-
For a port that has already joined the Voice VLAN, all packets are
assigned to the Voice VLAN as described in the
Interface Settings
-
Only packets that come from IP phones (based on the source OUI MAC
address prefix) by using the procedure described in the
VLAN Interface Settings
•
Enter Voice VLAN Class of Service (with or without remarking the packet
VPT) by using the Voice VLAN Properties Page. When remark is selected,
the switch changes the 802. 1 p priority of the packet at egress. Set the
remarking option as described in the
section.
•
Configure and update the Telephony OUI table with up to 128 entries (each
entry is a three-octet number) as described in the
OUI
section. The switch uses the table to determine if a port has Auto Voice
VLAN Membership enabled and will join the voice VLAN.
•
Enter the Voice VLAN aging time as described in the
VLAN Properties
