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.
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.
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.
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.
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

The first line indicates:
•
•
the number of the condition within that filter which matched the packet and consequently
caused a discard action,

•
the point at which the filter was applied, or a designation of global. For an IP network in-
terface, this will be the configured name of the interface. For a device-based filter, this will
be the configured device’s name.

The next lines contain a brief decode of the packet which was discarded. In particular, the
packet fields which comprise the packet type comparisons are displayed. The key IP fields are
