Small Office Remote Access Switch 515S YSTEM COMMANDSIP Routing Commandsfr congDisplays the congestion control information for the last 32 Rate Measurement Intervals for thecurrently selected access and DLCI. It is provided mainly for debug support of frame relayPVCs in order to monitor PVC usage.IP R OUTING C OMMANDSIn order to use the following commands, you must properly configure and initialize IP routingoperating mode. In addition, you must enable RIP to use the ip rip commands.The following commands are used to display IP routing information:ip addrpoolDisplays 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 theorigin 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 arpDisplays the current ARP cache table. The IP address, its corresponding MAC address, the typeof ARP table (dynamic or static), and the corresponding interface name are displayed.ip filter trace Controls the tracing of packets which are discarded as a result of IP filters. Issuing thecommand 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 alldiscarded packets due to filtering. As such, it should be enabled judiciously, as it has thepotential to fill the report log.discardEnables the tracing of packets which are discarded. When enabled, each discarded packet willcause a log report of the following format:(F) _:_:_:_:# 9a00 [IPFILT] /condition # at /in/out{IP} Src: xxx.xxx.xxx.xxx Dst: xxx.xxx.xxx.xxx Pr: n{UDP} Src: n Dst: nThe first line indicates:• the number of the condition within that filter which matched the packet and consequentlycaused 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 willbe 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, thepacket fields which comprise the packet type comparisons are displayed. The key IP fields are
