Administering PAD, X.25, and Frame Relay
Using the Set commands to configure Frame Relay
MAX Administration Guide
8-9
A Frame Relay concentrator concentrates many low-speed, dial-in connections into one
high-speed, nailed-up connection to a Frame Relay switch. As a Frame Relay concentrator, the
MAX forwards many lower-speed PPP connections onto one or more high-speed Frame Relay
interfaces.
A Frame Relay switch sends Frame Relay data out to the Frame Relay network. As a Frame
Relay switch, the MAX receives frames on one interface and transmits them on another
interface. The decision to forward frames onto the Frame Relay interface is made at OSI layer
2. The MAX router software is not involved. To use the MAX as a switch, you must configure
a circuit that pairs two Frame Relay interfaces. Instead of going to the Layer 3 router for a
decision on which interface to forward the frames, the MAX relies on the circuit configuration
to relay the frames received on one interface to its paired interface. A circuit is defined in two
Connection or RADIUS profiles.
Using the Set commands to configure Frame Relay
Use Set FR commands to dial and hang up the Frame Relay datalink and to remove the
RADIUS Frame Relay datalink profile. With this command, you bring down the nailed
connection specified in the named Frame Relay profile and the unit reestablishes the
connection within a few seconds. The Set Circuit commands let you activate or deactivate a
Frame Relay circuit.
Use the Set commands summarized in Table 8-5 to administer Frame Relay on the MAX unit.
