Description
Specify the action taken when packets with new source MAC addresses are received after the MAC address limit is reached. If this statement is not configured, packets with new source MAC addresses are forwarded by default.
The packet-action statement is not supported
on the QFX10002-60C switch.
Default
On a QFX Series Virtual Chassis, if you include the shutdown option at the [edit vlans vlan-name switch-options interface interface-name interface-mac-limit
packet-action] hierarchy level and issue the commit operation, the system generates a commit error. The system does
not generate an error if you include the shutdown option
at the [edit switch-options interface interface-name interface-mac-limit packet-action] hierarchy level.
Disabled. The default is for packets for new source MAC addresses to be forwarded after the MAC address limit is reached.
Options
| drop |
(EX Series switches, QFX Series switches, and PTX Series routers in which Junos OS Evolved is installed) Drop packets with new source MAC addresses, and do not learn the new source MAC addresses. Note:
On QFX10000 switches, if you include the drop option, you cannot configure unicast reverse-path forwarding (URFP) on integrated routing and bridging (IRB) and MAC limiting on the same interface. If you have an MC-LAG configuration, you cannot configure MAC limiting on the interchassis link (ICL) interface. |
| drop-and-log | (EX Series switches, QFX Series switches, and PTX Series routers in which Junos OS Evolved is installed) Drop packets with new source MAC addresses, and generate an alarm, an SNMP trap, or a system log entry. |
| log |
(EX Series switches and QFX Series switches) Hold packets with new source MAC addresses, and generate an alarm, an SNMP trap, or a system log entry. (PTX Series routers in which Junos OS Evolved is installed) Forward packets with the new source MAC addresses, and generate an alarm, an SNMP trap, and a system log entry when the MAC limit exceeds the configured value. |
| none | (EX Series switches, QFX Series switches, and PTX Series routers in which Junos OS Evolved is installed) Forward packets with new source MAC addresses. |
| shutdown | (EX Series switches, QFX Series switches, and PTX Series routers in which Junos OS Evolved is installed) Disable the specified interface, and generate an alarm, an SNMP trap, or a system log entry. |

Release Information
Statement introduced in Junos OS Release 8.4.
Support for the switch-options statement added in Junos OS
Release 9.2.
Support for top-level configuration for the virtual-switch type of
routing instance added in Junos OS Release 9.2. In Junos OS Release 9.1 and earlier,
the routing instances hierarchy supported this statement only for a VPLS instance or
a bridge domain configured within a virtual switch.
Support for logical systems added in Junos OS Release 9.6.
