NOTE: Layer 3 interfaces on trunk ports allow the interface to transfer trafficbetween multiple VLANs. Within a VLAN, traffic is bridged, while acrossVLANs, traffic is routed.You can display the configuration settings:user@switch> show interfaces vlan terseInterface Admin Link Proto Local Remotevlan up upvlan.111 up up inet 111.111.111.1/24user@switch> show vlansName Tag InterfacesdefaultNoneemployee-vlan 20ge-1/0/0.0, ge-1/0/1.0, ge-1/0/2.0marketing 40ge-1/0/10.0, ge-1/0/20.0, ge-1/0/30.0support 111ge-0/0/18.0mgmtbme0.32769, bme0.32771*user@switch> show ethernet-switching tableEthernet-switching table: 1 entries, 0 learnedVLAN MAC address Type Age Interfacessupport 00:19:e2:50:95:a0 Static - RouterRelatedDocumentationExample: Setting Up Bridging with Multiple VLANs for J-EX Series Switches on page 1070•• Example: Connecting an Access Switch to a Distribution Switch on page 1078• Example: Configuring IP Directed Broadcast on a J-EX Series Switch on page 904• Understanding Bridging and VLANs on J-EX Series Switches on page 1041Configuring MAC Table Aging (CLI Procedure)The aging process ensures that the J-EX Series switch tracks only active nodes on thenetwork and that it is able to flush out network nodes that are no longer available.To manage MAC entries more efficiently, you can configure an entry's aging time, whichis the maximum time that an entry can remain in the Ethernet Switching table before it“ages out”.To configure how long entries remain in the Ethernet Switching table before expiring,using the CLI (here, the VLAN is employee-vlan):[edit vlans employee-vlan]user@switch# set mac-table-aging-time 200RelatedDocumentationUnderstanding Bridging and VLANs on J-EX Series Switches on page 1041•• Example: Setting Up Basic Bridging and a VLAN for a J-EX Series Switch on page 10631138Dell PowerConnect J-Series Ethernet Switch Complete Software Guide for Junos OS
