The value can be specified in decimal or hexadecimal. The SNAP type field can be found a byte offset 20 in 802.3 SNAP formatted packets. Ethernet/Ingress Only IP-TOS IP TOS field. In place of the numeric value, you can specify one of the following text synonyms (the field values are also listed): minimize-delay 16 (0x10), maximize-reliability 4(0x04), minimize-cost2 (0x02), and normal-service 0(0x00). All IP/Ingress and Egress fragments IP fragmented packet. FO > 0 (FO = Fragment Offset in IP header)a All IP, no L4 rules/Ingress only first-fragments Non-IP fragmented packet or first fragmented packet. FO==0. All IP/Ingress only protocol IP protocol field. For IPv6b, this matches the Next Header field in the packet. In place of the numeric value, you can specify one of the following text synonyms (the field values are also listed): egp(8), esp(5), gre(47), icmp(1), igmp(2), ipip(4), ipv6(41), ospf(89), pim(102), rsvp(46), tcp(6), or udp(17). All IP/Ingress and Egress vlan-id Matches the VLAN tag number or the VLAN ID which is given All IP/Ingress to a VLAN when created. The ACL rule can only be applied to ports or any, and not VLANs. a. See the section Fragmented packet handling on page 311 for details. b. See the section IPv6 Traffic with L4 Match Conditions on page 311 for details about specifying a protocol/port match with IPv6. Note: Directed ARP response packets cannot be blocked with ACLs from reaching the CPU and being learned. Along with the data types described in Table 32, you can use the operators = to specify match conditions. For example, the match condition, source-port > 190, will match packets with a source port greater than 190. Be sure to use a space before and after an operator. Table 32. ACL Match Condition Data Types Condition Data Type Description prefix IP source and destination address prefixes. To specify the address prefix, use the notation prefix/prefix-length. For a host address, prefix-length should be set to 32. number Numeric value, such as TCP or UDP source and destination port number, IP protocol number. 310 | Chapter 13. ACLs
