Monitoring and Maintaining the MWR 1941-DC Router
To monitor and maintain the MWR 1941-DC router (including the multilink, VWIC, and FE interfaces)
and to view information about the PPP mux and header compression configuration, use the following
commands:
Command
Router# clear counters fastethernet slot/port
Router# clear ip rtp header-compression
Router# clear ppp mux interface
Router# show controllers fastethernet slot/port
Router# show controllers t1 slot/port
Router# show ip rtp header-compression
Router# show interfaces fastethernet slot/port
Router# show ppp multilink
Router# show ppp multilink interface number
Router# show ppp mux interface interface
Router# show redundancy
Router# show standby
Keepalives must be set for all Ethernet interfaces to ensure proper redundant behavior. A keepalive
value of 1 has been selected for maximum responsiveness.
Configuring no ip proxy-arp is helpful to avoid confusion with routes and ARP caches.
In a redundant configuration, both MWR 1941-DCs share a common IP address for their Multilink
interface.
Monitoring and Maintaining the MWR 1941-DC Router
Purpose
Clears interface counters.
Clears RTP header compression structures and
statistics.
Clears the PPP multiplexing interface counters.
Displays information about initialization block,
transmit ring, receive ring and errors for the Fast
Ethernet controller chip.
Displays information about the cable length,
framing, firmware, and errors associated with the
T1. With the MWR 1941-DC, this command also
displays the status of the relays on the VWIC.
Displays RTP header compression statistics.
Displays the status of the FE interface.
Displays MLP and multilink bundle information.
Displays multilink information for the specified
interface.
Displays statistics for PPP frames that have passed
through a given multilink interface.
Displays current redundant setting and recent
changes in state.
Displays HSRP configuration information.
