dialer-list protocol




dialer-list dialer-group protocol protocol-name {permit | deny | list access-list-number | access-group}

no dialer-list dialer-group [protocol protocol-name {permit | deny | list access-list-number | access-group} ]

Syntax Description:


Number of a dialer access group identified in any dialer-group interface configuration command


One of the following protocol keywords: appletalk, bridge, clns, clns_es, clns_is, decnet, decnet_router-L1, decnet_router-L2, decnet_node, ip, ipx, vines, or xns


Permits access to an entire protocol


Denies access to an entire protocol


Specifies that an access list will be used for defining a granularity finer than an entire protocol


Access list numbers specified in any DECnet, Banyan VINES, IP, Novell IPX, or XNS standard or extended access lists, including Novell IPX extended service access point (SAP) access lists and bridging types. See Table for the supported access list types and numbers.


Filter list name used in the clns filter-set and clns access-group commands

Command Description:

To define a dial-on-demand routing (DDR) dialer list to control dialing by protocol or by a combination of a protocol and a previously defined access list, use the dialer-list global configuration command. To delete a dialer list, use the no form of this command.


Dialing occurs when an interesting packet (one that matches access list specifications) needs to be output on an interface. Using the standard access list method, packets can be classified as interesting or uninteresting. In the following example, IGRP TCP/IP routing protocol updates are not classified as interesting and do not initiate calls:

Router(config)#access-list 101 deny igrp


The following example classifies all other IP packets as interesting and permits them to initiate calls:

Router(config)#access-list 101 permit ip

Then the following command places list 101 into dialer access group 1:

Router(config)#dialer-list 1 protocol ip list 101
