remark
No comments are added to describe entries in an IPv4 or IPv6 ACL.
IPv4 ACL configuration mode
IPv6 ACL configuration mode
You can add a comment by entering the
remark command immediately preceding an ACL entry. The comment appears in the output of
show commands that display ACL information.
The
no form of the command deletes the comment text added for an ACL entry.
The following example configures remarks for an IPv4 ACL.
device(config)# ip access-list extended tcp_udp device(config-ext-ipacl-tcp_udp)# remark The following line permits TCP packets device(config-ext-ipacl-tcp_udp)# permit tcp 192.168.4.40/24 2.2.2.2/24 device(config-ext-ipacl-tcp_udp)# remark The following permits UDP packets device(config-ext-ipacl-tcp_udp)# permit udp 192.168.2.52/24 2.2.2.2/24 device(config-ext-ipacl-tcp_udp)# deny ip any any
The following example configures remarks for an IPv6 ACL.
device(config)# ipv6 access-list rtr device(config-ipv6-access-list rtr)# remark This entry permits ipv6 packets from 2001:DB8::2 to any destination device(config-ipv6-access-list rtr)# permit ipv6 host 2001:DB8::2 any device(config-ipv6-access-list rtr)# remark This entry denies udp packets from any source to any destination device(config-ipv6-access-list rtr)# deny udp any any device(config-ipv6-access-list rtr)# remark This entry denies IPv6 packets from any source to any destination device(config-ipv6-access-list rtr)# deny ipv6 any any
The following example shows the comment text for the ACL named "rtr" in a show running-config display.
device# show running-config ipv6 access-list rtr remark This entry permits ipv6 packets from 2001:DB8::2 to any destination permit ipv6 host 2001:DB8::2 any remark This entry denies udp packets from any source to any destination deny udp any any remark This entry denies IPv6 packets from any source to any destination deny ipv6 any any
