• 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
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.
• In or Out, corresponding to INPUT or OUTPUT application.
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
always displayed on one line. If the IP protocol is one of the explicitly recognized values (ICMP,
UDP, TCP) the next line will contain a decode of the key fields of that protocol.
off
Disables the trace.
ip ping <host IP address> [timeout /dnnnn]
Sends an ICMP Echo message to a specified host. The parameters for this command are:
host IP address
IP address using dotted decimal notation for the target host.
timeout
Optional parameter that indicates the number of seconds to wait for an ICMP Echo Reply
Message. The valid range for the time out value is 1 to 60. The default value is 10.
