Command History Version 8.2.1.0 Allows ACL control of fragmented packets for IP (Layer 3) ACLs.Version 8.1.1.0 Introduced on the E-Series ExaScale.Version 7.4.1.0 Added the monitor option.Version 6.5.10 Expanded to include the optional QoS order priority for the ACLentry.UsageInformationThe monitor option is relevant in the context of flow-based monitoring only. For moreinformation, refer to Port Monitoring.The order option is relevant in the context of the Policy QoS feature only. The followingapplies:• The seq sequence-number command is applicable only in an ACL group.• The order option works across ACL groups that have been applied on an interfacevia the QoS policy framework.• The order option takes precedence over seq sequence-number.• If sequence-number is not configured, the rules with the same order value areordered according to their configuration order.• If sequence-number is configured, the sequence-number is used as a tie breakerfor rules with the same order.When you use the log option, the CP processor logs details about the packets that match.Depending on how many packets match the log entry and at what rate, the CP may becomebusy as it has to log these packets’ details.You cannot include IP, TCP, or UDP (Layer 3) filters in an ACL configured with ARP or Ether-type (Layer 2) filters. Apply Layer 2 ACLs to interfaces in Layer 2 mode.NOTE: When ACL logging and byte counters are configured simultaneously, byte countersmay display an incorrect value. Configure packet counters with logging instead.seq ether-typeConfigure an egress filter with a specific sequence number that filters traffic with specified types of Ethernet packets.This command is supported only on 12-port GE line cards with SFP optics. For specifications, refer to your line carddocumentation.E-SeriesSyntax seq sequence-number {deny | permit} ether-type protocol-type-number {destination-mac-address mac-address-mask | any} vlanvlan-id {source-mac-address mac-address-mask | any} [count[byte] | log] [order] [monitor]To remove this filter, use the no seqsequence-number command.Parameterssequence-numberEnter a number from 0 to 4294967290.deny Enter the keyword deny to drop all traffic meeting the filter criteria..257
