IP Routing Commands
Access. In particular, the DLCI list is maintained within the code to identify all DLCIs for which
the network has knowledge, but which are not currently configured. This list is updated when
unknown DLCIs are noted through the
LMI FULL REPORT STATUS
messages, or through
CLLM messages.
fr dbg level <level>
Displays or sets the current debug level for frame relay. If the level parameter is not specified,
then the current debug level is displayed. The debug level corresponds to an internal variable
that controls how much information is written to the system log as frame relay events occur.
Possible settings for this parameter are 0 through 2, with 0 being the least informative and 2
being the most informative.
fr cong
Displays the congestion control information for the last 32 Rate Measurement Intervals for the
currently selected access and DLCI. It is provided mainly for debug support of frame relay
PVCs in order to monitor PVC usage.

In order to use the following commands, you must properly configure and initialize IP routing
operating mode. In addition, you must enable RIP to use the ip rip commands.
The following commands are used to display IP routing information:
ip addrpool
Displays the current IP address pool. There are three fields displayed: address, origin, and in use:
•
address: lists the IP address in the pool
•
origin: specifies how the IP address has come to be placed into the IP address pool. If the
origin is DHCP, the IP address was obtained from a DHCP server. If the origin is STATIC,
the IP address was manually configured via CFGEDIT.
•
in use: specifies whether or not the IP address has been leased to a remote IP host device.
ip arp
Displays the current ARP cache table. The IP address, its corresponding MAC address, the type
of ARP table (dynamic or static), and the corresponding interface name are displayed.
ip filter trace <discard> <off>
Controls the tracing of packets which are discarded as a result of IP filters. Issuing the
command without an optional parameter acts as a query to the current state of the trace.
The purpose of this command is to aid in the initial debug of IP filters, providing a list of all
discarded packets due to filtering. As such, it should be enabled judiciously, as it has the
potential to fill the report log.
discard
Enables the tracing of packets which are discarded. When enabled, each discarded packet will
cause a log report of the following format:
(F) _:_:_:_:# 9a00 [IPFILT] <filtername>/condition # at <application point name>/in/out
{IP} Src: xxx.xxx.xxx.xxx Dst: xxx.xxx.xxx.xxx Pr: n
{UDP} Src: n Dst: n
