Making Frame Relay Connections
After the hardware is installed, use the addyred command to reconfigure the node to recognize the card redundancy. Refer to the Cisco WAN Switching Command Reference for more information on the commands addyred, delyred, dspyred, and ptyred.
Setting Up Frame Relay Ports and Connections (FRM)
This section outlines the steps for setting up and deleting Frame Relay ports, adding and configuring connections, and bundling connections. As the steps show, some commands apply to channelized connections (T1, E1, or J1) but not to unchannelized connections (V.35 or X.21). Use either the IGX control terminal or a Cisco WAN Manager workstation to execute the commands. For parameters and other details on the commands, refer to the Cisco WAN Switching Command Reference.
If a port has multiple PVCs, you can optionally bundle the connections. Bundling facilitates network meshing. You can specify connection bundling during parameter specification in the Add Connection (addcon) command: if you press Return without specifying a DLCI during port specification, the system prompts for bundling information. See the “Frame Relay Connections” chapter in the Cisco WAN Switching Command Reference for details.
Step 1 If not already done, activate the applicable lines with the upln command.
Step 2 Use the dspcds command to verify that all nodes have the correct FRI back card and FRM front card. (Use the vt command to gain access to other nodes.) The dspcds output shows the slot number of each card and any mismatch between firmware on the front card and firmware on the back card. Note the slot number of each FRM or UFM for subsequent commands.
Step 3 For V.35 and X.21 interfaces, check the mode (DCE or DTE) of each relevant port by using the dspfrport command. (For T1 and E1 lines, the mode is not applicable.) On an
Note Jumper cards for selecting the mode of a V.35 or X.21 interface have an impedance of either 100 ohms or 200 ohms. At higher speeds on ports with
Step 4 For optional
For V.35 and X.21 interfaces, skip the next three steps.
Step 5 For T1, E1, and J1 interfaces, bring up the line using the upln command.
Step 6 For T1, E1, and J1 interfaces, configure the line using the cnfln command.
Step 7 For T1, E1, and J1 interfaces, add the logical Frame Relay port using the addport command.
Step 8 For all interface types, activate the port using the upport command.
Step 9 Configure the port for speed, clocking, LMI type, and so on, by using the cnffrport command. Alternatively, you can keep the default parameters.
If you intend to bundle connections, use cnffrport to set the Port ID to the DLCI planned at the
