EX2500 Ethernet Switch Configuration Guide
As shown in Figure 5, the tagged packet remains unchanged as it leaves the switch through port 5, which is configured as a tagged member of VLAN 2. However, the tagged packet is stripped (untagged) as it leaves the switch through port 7, which is configured as an untagged member of VLAN 2.

VLAN Topologies and Design Considerations
This section discusses how you can connect users and segments to a host that supports many logical segments or subnets by using the flexibility of the multiple VLAN system. Be aware of the following VLAN properties on the EX2500 switch:
By default, the EX2500 software is configured so that tagging is disabled on all ports.
By default, the EX2500 software is configured so that all data ports are members of VLAN 1.
By default, the EX2500 software is configured so that the management port is a member of VLAN 4095 (the management VLAN).
If you configure Spanning Tree, note that Spanning Tree Groups
VLAN Configuration Rules
VLANs operate according to specific configuration rules. When creating VLANs, consider the following rules that determine how the configured VLAN reacts in any network topology:
All ports involved in trunking and port mirroring must have the same VLAN configuration. If a port is on a trunk with a mirroring port, the VLAN configuration cannot be changed. For more information trunk groups, see “Port Trunking Configuration Example” on page 45.
