Configuring Synchronous Services
Viewing the Configured WAN Protocol
You can view the WAN protocol that is enabled on a synchronous circuit.
However, do not change the current value.
Caution: Changing the WAN protocol does not reconfigure the interface, and
could disable the interface.
Using the BCC
To view the configured WAN protocol, navigate to the serial prompt (for example,
box; serial/2/1) and type:
serial/2/1# wan-protocol ?
The configured WAN protocol is listed as the current value.
Using Site Manager
See the WAN Protocol parameter on page A-79 for information.
Setting Pass-Through Addresses
You can assign a local media access control (MAC) address to the local interface
using the Pass Thru Local Address parameter. This address becomes the source
address of packets that are bridged to the destination MAC address.
You assign the destination MAC address using the Pass Thru Remote Address
parameter. This address becomes the destination MAC address of packets that are
bridged to the local MAC address.
Always reverse the local and remote MAC addresses at the remote synchronous
pass-through interface.
When assigning addresses, use any unique MAC address of exactly 12
hexadecimal digits. Make sure that the second digit in the address is a zero
(for example, 10fffabc5432).
