Standard IPX Access Lists

The access lists are used to filter the traffic coming and going through the router. There are two possibilities of the list either the data packet is denied or permitted to pass. The standard IPX list has the cool feature of monitoring the packet by there source and destination addresses, previously it could not be done.

To define a standard IPX access list, the simple standard access-list command can be used. The standard IPX access lists are ranging from 800-899. The standard

IPX access list can also define an individual hosts having a place in the network.

RouterA(config)#access-list 850 deny 101A 101B

The above statement recognize the access list entry as a part of standard IPX access list 850, that blocks the traffic from the root network 101A to go to the final destination at (101B). The next task is to permit the traffic to pass through the router.

Observe that there is no separate keyword for any of the individual host. The above statement is same as if it is saying “permit any traffic from any network”.

If you want to see all the access lists that are defined on the on the router than you can use the following command of:

RouterA#sh ipx access-list
IPX standard access list 850
deny 101A 101B
permit FFFFFFFF FFFFFFFF

A specific IPX list that is combined to a certain interface can be viewed. One of its output is as follows:

RouterA#show ipx int e1
the Ethernet1 is up, line protocol is up
the IPX address is 101B.0060.5cc4.f41b, NOVELL-ETHER [up]
the Delay of this IPX network, in ticks is 1 throughput 0 link delay 0
the IPXWAN processing not enabled on this interface.
the IPX SAP update interval is 60 seconds
the IPX type 20 propagation packet forwarding is disabled
the Incoming access list is not set
the Outgoing access list is 850
