Command

Purpose

 

 

 

Step 20 Router(config)# access-listaccess-list-number

Creates an access list.

 

{permit deny} source source-mask [destination

The keywords and arguments are as follows:

 

destination-mask] {eq neq} [[source-object]

 

[destination-object] [identification] any]

• access-list-number—Specifies the integer that

 

 

 

 

 

 

 

 

you choose. The number should be between 300

 

 

 

 

and 399, and it uniquely identifies the access list.

 

 

 

 

• permit—Permits access when there is an address

 

 

 

 

match.

 

 

 

 

• deny—Denies access when there is an address

 

 

 

 

match.

 

 

 

 

• source—Specifies the source address. DECnet

 

 

 

 

addresses are written in the form area.node. For

 

 

 

 

example, 50.4 is node 4 in area 50. All addresses

 

 

 

 

are in decimal.

 

 

 

 

• source-mask—Specifies the mask to be applied

 

 

 

 

to the address of the source node. All masks are

 

 

 

 

in decimal.

 

 

 

 

• destination—(Optional) Specifies the DECnet

 

 

 

 

address of the destination node in decimal

 

 

 

 

format. DECnet addresses are written in the form

 

 

 

 

area.node. For example, 50.4 is node 4 in area 50.

 

 

 

 

All addresses are in decimal.

 

 

 

 

• destination-mask—(Optional) Specifies the

 

 

 

 

destination mask. DECnet addresses are written

 

 

 

 

in the form area.node. For example, 50.4 is node

 

 

 

 

4 in area 50. All masks are in decimal.

 

 

 

 

• eq—Specifies that the item matches the packet if

 

 

 

 

all the specified parts of the source object,

 

 

 

 

destination object, and identification match the

 

 

 

 

data in the packet.

 

 

 

 

• neq—Specifies that the item matches the packet

 

 

 

 

if any of the specified parts do not match the

 

 

 

 

corresponding entry in the packet.

 

 

 

 

• source-object—(Optional) Contains the

 

 

 

 

mandatory keyword src and one of the following

 

 

 

 

optional keywords:

 

 

 

 

– eq neq lt gt—Specifies equal to, not

 

 

 

 

equal to, less than, or greater than. These

 

 

 

 

keywords must be followed by the argument

 

 

 

 

object-number, a numeric DECnet object

 

 

 

 

number.

 

 

 

 

– exp—Stands for expression; followed by a

 

 

 

 

regular-expression that matches a string. See

 

 

 

 

the “Regular Expressions” appendix in the

 

 

 

 

Cisco IOS Dial Technologies Command

 

 

 

 

Reference for a description of regular

 

 

 

 

expressions.
