Data-plane ACL

Table 3 Data-plane ACL

Command	Purpose
access-list table_name {l2\|l3\|l3v6\|mirror\|mirrorv6\|flow_control} {ingress\|egress}	Add a data-plane ACL table.
bind interface {{ethernet\|link-aggregation} interface_name\|all}	Apply the ACL table to the interface.

access-list

[Command] access-list table_name {l2|l3|l3v6|mirror|mirrorv6|flow_control} {ingress|egress}

[Purpose] Add a data-plane ACL table.

[Parameters]

Parameter	Description
table_name	ACL table name.

[View] Global Configuration View

[Notes] ACLs of type L2/L3/L3v6 are used for Layer 2/Layer 3/Layer 3 IPv6 traffic forwarding, respectively. Mirror/Mirrorv6 are used to local mirror SPAN and remotely mirror ERSPAN. Flow_Control are usually used together with Policer module to implement rate limiting for specific flows. Run command no access-list table_name to delete the ACL table.

[Use Cases]

sonic# configure terminal
sonic(config)# access-list TABLE_1 flow_control ingress
sonic(config)# access-list TABLE_3 l3 egress

bind interface {{ethernet|link-aggregation}

[Command] bind interface {{ethernet|link-aggregation} interface_name|all}

[Purpose] Apply the ACL table to the interface.

[Parameters]

Parameter	Description
interface_name	Interface name (eg.0/1)
all	Binds to all interfaces.

[View] ACL table Configuration View

[Notes] ACL table is for ports. When you bind an ACL table to some ports, it means that the ACL table is valid for the traffic on these ports. An ACL table can be bound to multiple ports, and a port can also have multiple ACL tables, which means a “many-to-many” relationship. Run command no bind interface {{ethernet|link-aggregation} interface_name|all} to unbind the interface.

[Use Cases]

sonic# configure terminal
sonic(config)# access-list TABLE_1 l3 ingress
sonic(config-l3-acl-table_1)# bind interface ethernet 0/1
sonic(config-l3-acl-table_1)# bind interface all
