Using an ACL to restrict SSH access
6
DRAFT: BROCADE CONFIDENTIAL
Syntax: show access-list bindings
Using an ACL to restrict SSH access
To configure an ACL that restricts SSH access to an IPv6 device, create the named ACL with the ACL
statements, and then use the ssh access-group ipv6 command to restrict SSH access for IPv6.
ServerIronADX(config)# ipv6 access-list test2
ServerIronADX(config-ipv6-access-list test2)# deny ipv6 host 2001:db8:1::1 any
log
ServerIronADX(config-ipv6-access-list test2)# permit ipv6 2001:db8:1::0/32 any
ServerIronADX(config-ipv6-access-list test2)# permit ipv6 2001:db8:2::0/32 any
ServerIronADX(config-ipv6-access-list test2)# permit ipv6 host 2001:db8:3::1 any
ServerIronADX(config-ipv6-access-list test2)# exit
ServerIronADX(config)# ssh access-group ipv6 test2
Syntax: [no] ssh access-group ipv6 <acl-name>
Using an ACL to restrict Telnet access
To configure an ACL that restricts Telnet access to an IPv6 device, create the named ACL with the
ACL statements, and then use the telnet access-group ipv6 command to restrict Telnet access for
IPv6.
ServerIronADX(config)# ipv6 access-list test1
ServerIronADX(config-ipv6-access-list test1)# deny ipv6 host 2001:db8:1::1 any
log
ServerIronADX(config-ipv6-access-list test1)# permit ipv6 2001:db8:1::0/32 any
ServerIronADX(config-ipv6-access-list test1)# permit ipv6 2001:db8:2::0/32 any
ServerIronADX(config-ipv6-access-list test1)# permit ipv6 host 2001:db8:3::1 any
ServerIronADX(config-ipv6-access-list test1)# exit
ServerIronADX(config)# telnet access-group ipv6 test1
Syntax: telnet access-group ipv6 <acl-name>
Logging IPv6 ACLs
Logging for IPv6 ACLs is disabled by default. To enable logging, enable it for each IPv6 ACL, and
then include the logging option in an ACL statement. Logging at both levels must be configured in
order for statistics for packets that match the condition to be logged.
ServerIronADX(config)# ipv6 access-list acl2
ServerIronADX(config-ipv6-access-list-acl2)# logging-enable
ServerIronADX(config-ipv6-access-list-acl2)# permit tcp host 2001:db8:dabf any eq
http
ServerIronADX(config-ipv6-access-list-acl2)# permit ipv6 any any
Syntax: [no] logging-enable
NOTE
Syntax for the log option in an IPv6 ACL statement are presented in the section “IPv6 ACL syntax” on
page 102.
