Configuring Bisync

To configure PA-4T+ interfaces for Bisync operation in Cisco 7200 series routers, refer to the “Block Serial Tunneling (BSTUN)” section of the “Configuring Serial Tunnel (STUN) and Block Serial Tunnel (BSTUN)” chapter of the Bridging and IBM Networking Configuration Guide .

Checking the Configuration

After configuring the new interface, use the show commands to display the status of the new interface or all interfaces and the ping and loopback commands to check connectivity.

Using show Commands to Verify the New Interface Status

Use the following steps tiuse verify that the new interfaces are configured and operating correctly:

Step 1	Use the show version command to display the system hardware configuration. Ensure
	that the list includes the new serial interfaces.
Step 2	Display all the current interface processors and their interfaces with the show controllers
	command. Verify that the new PA-4T+ appears in the correct slot.
Step 3	Specify one of the new interfaces:
	• Cisco 7100 series, Cisco 7200 series or Cisco uBR7200 series routers—Use the
	show interfaces [type slot/port] command.
	• VIP2—Use the show interfaces type slot/port-adapter/port command.
	Verify that the first line of the display specifies the interface with the correct slot number.
	Also verify that the interface and line protocol are in the correct state: up or down.
Step 4	Display the protocols configured for the entire system and specific interfaces with the
	show protocols command. If necessary, return to configuration mode to add or remove
	protocol routing on the system or specific interfaces.
Step 5	Display the running configuration file with the	show running-config command. Display
	the configuration stored in NVRAM using the	show startup-config command. Verify

that the configuration is accurate for the system and each interface.

If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, contact a service representative for assistance.
