Cabletron Systems CSX1000, CSX1200 manual Disables the trace

USER’S GUIDE

•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.
