Vport
The virtual port associated with this service. For bridging services, there is a one-to-one 
mapping between a virtual port and a virtual circuit. For routing services, multiple virtual 
circuits may map to a single virtual port. For trunking services, multiple virtual ports can map 
to a single virtual circuit.
Description
The textual description given to this service when you set it up through the 
cas or mas 
command.
Service Type
A Frame Relay service may be 
Bridging, Routing or Trunking. All three service types are set up 
through the cas command. Bridging and Routing services may coexist on the same virtual 
circuit. Trunking cannot coexist with either Bridging or Routing on the same virtual circuit.
Modifying a Frame Relay Service
You can modify previously created Frame Relay services using the mas command. The mas 
command uses the same screen as the cas command. Simply enter mas, the slot, slash (/), 
port and service number. For example:
mas 2/3 1
would modify the first service on Port 3 for the WSX board in Slot 2. This command displays 
the same screen as the cas command. See the appropriate section for modifying the service 
type:
• Bridging See Configuring a Bridging Service on page 29-57.
• Routing See Configuring a WAN Routing Service on page 29-59.
• Trunking See Configuring a Trunking Service on page 29-62.
