The access table is a series of rules that the manager adds to control data packets input and output in the vro. It is not generated by the router itself. The Access Table allows or disables data packets from entering or outputting to the destination. The table items for accessing the table are executed sequentially. When the data packet arrives, the system first checks whether it is restricted by the first table item. If not, it is executed sequentially; if it matches the first table item, you do not have to perform the following table item check whether it is allowed or disabled.
Each Protocol of each interface can have only one access table.
The number of an access table can be determined. The specific protocol and its corresponding access table number are as follows:
◆ I P standard Access Table No.: 1 ~ 9 9
◆ I P extended access table No.: 1 0 0 ~ 1 9 9
◆ I P X standard Access Table No.: 8 0 0 ~ 8 9 9
◆ I P X extended access table No.: 1 0 0 0 ~ 1 0 9 9
◆ AppleTa l k Access Table No.: 6 0 0 ~ 6 9 9
Note: In Cisco IOS Release11.2 or later versions, you can use the famous access table to determine the number between 1 and later ~ 199 access table.
