Synchronous Interface Configuration
interface moxa-c502
Description
Moxa c502 synchronous interface is shown under the interfaces list with the name moxa-c502-N
Property Description
name (name; default: moxa-c502-N) - interface name
cisco-hdlc-keepalive-interval (time; default: 10s) - keepalive period in seconds
clock-rate (integer; default: 64000) - speed of internal clock
clock-source (external | internal | tx-from-rx | tx-internal; default: external) - clock source
frame-relay-dce (yes | no; default: no) - operate or not in DCE mode
frame-relay-lmi-type (ansi | ccitt; default: ansi) - Frame-relay Local Management Interface type:
• ansi - set LMI type to ANSI-617d (also known as Annex A)
• ccitt - set LMI type to CCITT Q933a (also known as Annex A)
ignore-dcd (yes | no; default: no) - ignore or not DCD
line-protocol (cisco-hdlc | frame-relay | sync-ppp; default: sync-ppp) - line protocol name
mtu (integer; default: 1500) - Maximum Transmit Unit
Notes
There will be TWO interfaces for each MOXA C502 card since the card has TWO ports.
The Wandy driver for the MOXA C502 Dual Synchronous adapter allows you to unplug the
V.35 cable from one modem and plug it into another modem with a different clock speed, and you
do not need to restart the interface or router.
Example
[admin@Wandy] interface> moxa-c502
[admin@Wandy] interface moxa-c502> print
Flags: X - disabled, R - running
0 R name="moxa-c502-1" mtu=1500 line-protocol=sync-ppp clock-rate=64000
clock-source=external frame-relay-lmi-type=ansi frame-relay-dce=no
cisco-hdlc-keepalive-interval=10s
1 R name="moxa-c502-2" mtu=1500 line-protocol=sync-ppp clock-rate=64000
clock-source=external frame-relay-lmi-type=ansi frame-relay-dce=no
cisco-hdlc-keepalive-interval=10s
[admin@Wandy] interface moxa-c502>
You can monitor the status of the synchronous interface:
[admin@Wandy] interface moxa-c502> monitor 0
dtr: yes
rts: yes
cts: no
dsr: no
dcd: no
[admin@Wandy] interface moxa-c502>
Connect a communication device, e.g., a baseband modem, to the V.35 port and turn it on. If the
link is working properly the status of the interface is:
[admin@Wandy] interface moxa-c502> monitor 0
