DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide ICMP-MESSAGE (Optional) Specifies the ICMP message. The following pre-defined parameters are available for selection: beyond-scope, destinationunreachable, echo-reply, echo-request, header, hop-limit, mld-query, mld-reduction, mld-report, nd-na, nd-ns, next-header, no-admin, noroute, packet-too-big, parameter-option, parameter-problem, portunreachable, reassembly-timeout, redirect, renum-command, renumresult, renum-seq-number, router-advertisement, router-renumbering, router-solicitation, time-exceeded, unreachable. Default None. Command Mode Extended Expert Access-list Configuration Mode. Command Default Level Level: 12. Usage Guideline If a rule entry is created without a sequence number, a sequence number will be automatically assigned. If it is the first entry, the sequence number 10 is assigned. A subsequent rule entry will be assigned a sequence number that is 10 greater than the largest sequence number in that access list and is placed at the end of the list. The user can use the command access-list sequence to change the start sequence number and increment number for the specified access list. After the command is applied, the new rule without specified sequence number will be assigned sequence based new sequence setting of the specified access list. When you manually assign the sequence number, it is better to have a reserved interval for future lower sequence number entries. Otherwise, it will create extra effort to insert an entry with a lower sequence number. The sequence number must be unique in the domain of an access-list. If you enter a sequence number that is already present, an error message will be shown. Example This example shows how to use the extended expert ACL. The purpose is to deny all the TCP packets with the source IP address 192.168.4.12 and the source MAC address 00:13:00:49:82:72. Switch# configure terminal Switch(config)# expert access-list extended exp_acl Switch(config-exp-nacl)# deny tcp host 192.168.4.12 host 0013.0049.8272 any any Switch(config-exp-nacl)# end Switch# show access-lists Extended Expert access list exp_acl(ID: 9999) 10 deny tcp host 192.168.4.12 host 0013.0049.8272 any any Switch# 4-18 permit | deny (ip access-list) This command is used to add a permit or a deny entry. Use the no form of the command to remove an entry. 54
