DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide advertisement,router-solicitation,source-quench,source-route-failed, timeexceeded,timestamp-reply,timestamp-request,traceroute,ttl-expired,unreachable. Default None. Command Mode IP Access-list Configuration Mode. 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. To create a matching rule for an IP standard access list, only the source IP address or destination IP address fields can be specified. Example This example shows how to create four entries for an IP extended access list, named Strict-Control. These entries are: permit TCP packets destined to network 10.20.0.0, permit TCP packets destined to host 10.100.1.2, permit all TCP packets go to TCP destination port 80 and permit all ICMP packets. Switch# configure terminal Switch(config)#ip access-list extended Strict-Control Switch(config-ip-ext-acl)#permit tcp any 10.20.0.0 0.0.255.255 Switch(config-ip-ext-acl)#permit tcp any host 10.100.1.2 Switch(config-ip-ext-acl)#permit tcp any any eq 80 Switch(config-ip-ext-acl)#permit icmp any any Switch(config-ip-ext-acl)# This example shows how to create two entries for an IP standard access-list, named "std-acl". These entries are: permit IP packets destined to network 10.20.0.0, permit IP packets destined to host 10.100.1.2. Switch# configure terminal Switch(config)#ip access-list std-acl Switch(config-ip-acl)#permit any 10.20.0.0 0.0.255.255 Switch(config-ip-acl)#permit any host 10.100.1.2 Switch(config-ip-acl)# 4-12 permit | deny (ipv6 access-list) This command is used to add a permit entry or deny entry to the IPv6 access list. Use the no form of this command to remove an entry from the IPv6 access list. Extended Access List: 40

exceeded,timestamp-reply,timestamp-request,traceroute,ttl-expired,unreachable.
Default
None.
Command Mode
IP Access-list Configuration Mode.
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.
To create a matching rule for an IP standard access list, only the source IP address or destination IP address fields
can be specified.
Example
This example shows how to create four entries for an IP extended access list, named Strict-Control. These entries
are: permit TCP packets destined to network 10.20.0.0, permit TCP packets destined to host 10.100.1.2, permit all
TCP packets go to TCP destination port 80 and permit all ICMP packets.
Switch# configure terminal
Switch(config)#ip access-list extended Strict-Control
Switch(config-ip-ext-acl)#permit tcp any 10.20.0.0 0.0.255.255
Switch(config-ip-ext-acl)#permit tcp any host 10.100.1.2
Switch(config-ip-ext-acl)#permit tcp any any eq 80
Switch(config-ip-ext-acl)#permit icmp any any
Switch(config-ip-ext-acl)#
This example shows how to create two entries for an IP standard access-
list, named “std
-
acl”. These entries are:
permit IP packets destined to network 10.20.0.0, permit IP packets destined to host 10.100.1.2.
Switch# configure terminal
Switch(config)#ip access-list std-acl
Switch(config-ip-acl)#permit any 10.20.0.0 0.0.255.255
Switch(config-ip-acl)#permit any host 10.100.1.2
Switch(config-ip-acl)#

permit | deny (ipv6 access-list)
This command is used to add a permit entry or deny entry to the IPv6 access list. Use the
no
form of this
command to remove an entry from the IPv6 access list.
