VLANs and Port VLAN ID Numbers
VLAN Numbers
The EX2500 switch supports up to 1024 VLANs per switch. Even though the
maximum number of VLANs supported at any given time is 1024, each can be
identified with any number between 1 and 4094. VLAN 1 is the default VLAN for
the data ports. VLAN 4095 is used by the management network, which includes the
management port.
Use the following CLI command to view VLAN information:
ex2500(config)# show vlan
VLAN Name Status Ports
---- ------------------------ ------ -------------------------
1 VLAN 1 ena 1-24, po1-po36
2 VLAN 2 dis empty
4095 Mgmt VLAN ena MGMT
PVID Numbers
Each port in the switch has a configurable default VLAN number, known as its
PVID. By default, the PVID for all non-management ports is set to 1, which
correlates to the default VLAN ID. The PVID for each port can be configured to any
VLAN number between 1 and 4094.
Use the following CLI commands to view and configure PVIDs:
„ Port information:
ex2500# show interface information
Alias Port Tag Edge Lrn Fld PVID NAME VLAN(s)
----- ---- --- ---- --- --- ---- -------------- -----------------
1 1 y n e e 1 1 1
2 2 y n e e 1 2 1

5 5 y n e e 1 5 1
6 6 y n e e 1 6 1
... ... ... ...
24 24 n n e e 1 24 1

„ Port configuration:
ex2500(config)# interface port 7
ex2500(config-if)# pvid 7
Each port on the switch can belong to one or more VLANs, and each VLAN can
have any number of switch ports in its membership. Any port that belongs to
multiple VLANs, however, must have VLAN tagging enabled (see “VLAN Tagging”
on page 25).
