Wildcard Masks

When you specify source and destination IP addresses in an ACE, you must also include a mask for each in the form source-ip-addr mask and destination-ip-addr mask.

The mask is a wildcard mask. The security ACL checks the bits in IP addresses that correspond to any 0s (zeros) in the mask, but does not check the bits that correspond to 1s (ones) in the mask. Specify the IP address and wildcard mask in dotted decimal notation. For example, the IP address and wildcard mask 10.0.0.0 and 0.255.255.255 match all IP addresses that begin with 10 in the first octet.

Class of Service

Class-of-service (CoS) assignment determines the priority treatment of packets transmitted by a WX switch, corresponding to a forwarding queue on the MAP. Table 31 shows the results of CoS priorities you assign in security ACLs.
