4000 Router Series ACL and QoS Command Reference

lsap lsap-type lsap-type-mask: Matches the DSAP and SSAP fields in LLC encapsulation. The lsap-type

argument is a 16-bit hexadecimal number that represents the encapsulation format. The lsap-type-mask

argument is a 16-bit hexadecimal number that represents the LSAP mask.

type protocol-type protocol-type-mask: Matches one or more protocols in the Ethernet frame header. The

protocol-type argument is a 16-bit hexadecimal number that represents a protocol type in Ethernet_II and

Ethernet_SNAP frames. The protocol-type-mask argument is a 16-bit hexadecimal number that represents

a protocol type mask.

source-mac source-address source-mask: Matches a source MAC address range. The source-address

argument represents a source MAC address, and the sour-mask argument represents a mask in the H-H-H

format.

time-range time-range-name: Specifies a time range for the rule. The time-range-name argument is a

case-insensitive string of 1 to 32 characters. It must start with an English letter. If the time range is not

configured, the system creates the rule. However, the rule using the time range can take effect only after

you configure the timer range. For more information about time range, see ACL and QoS Configuration

Guide.

Usage guidelines

Within an ACL, the permit or deny statement of each rule must be unique. If the ACL rule you are creating

or editing has the same deny or permit statement as another rule in the ACL, your creation or editing

attempt fails.

You can edit ACL rules only when the match order is config. If no optional keywords are provided for the

undo rule command, you delete the entire rule. If optional keywords or arguments are provided, you

delete the specified attributes.

To view rules in an ACL and their rule IDs, use the display acl all command.

Examples

# Create a rule in Ethernet frame header ACL 4000 to permit ARP packets and deny RARP packets.

[Sysname-acl-ethernetframe-4000] rule permit type 0806 ffff
