Extended access-lists are holders for the elements that are configured to create the match criteria for a policy-based route (PBR).
You need to enter the Extended ACL ID number. You can set a sequence number (Sequence No.) for each entry. The sequence number is a number between 1 and 256.
The PBR match criteria that you define determine the path of a particular data traffic flow. At least one item must match the other items in the extended ACL.
To create an entry, enter the following information in the page fields:
Source IP Address / Netmask, an IPv4 address of the format www.xxx.yyy.zzz/mask (1-32).
Source Port, the exact port from which the traffic is coming (if specified).
Destination IP Aaddress / Netmask, an IPv4 address of the format www.xxx.yyy.zzz/mask (1-32).
Destination Port, the exact port to which you want the traffic routed (if specified).
Protocol, select a protocol such as TCP, UDP, ICMP, or ANY from the drop-down list. You can also choose NULL.
IP-TOS, which is an IP type of service (TOS) priority number between 1 and 255 (optional).
