To configure VLAN when you use IP (Internet Protocol) partnerships,
consider the following requirements and procedures.
- VLAN tagging is supported for IP partnership traffic between two
systems.
- VLAN provides network traffic separation at the layer 2 level
for Ethernet transport.
- VLAN tagging by default is disabled for any IP address of a node
port. You can use the command-line interface (CLI) to optionally set
the VLAN ID for port IPs on both systems in the IP partnership.
- When a VLAN ID is configured for the port IP addresses that are
used in remote copy port groups, appropriate VLAN settings on the
Ethernet network must also be properly configured to prevent connectivity
issues.
- Setting VLAN tags for a port is disruptive. Therefore, VLAN tagging
requires that you stop the partnership first before you configure
VLAN tags. Then, restart again when the configuration is complete.
Follow this procedure to configure VLAN tags for existing
IP partnership setups:
- Stop the partnership between the local and remote system.
- Configure VLAN on node ports in the remote copy port group
on the local system.
- Configure all intervening switches with appropriate VLAN
tags.
- Configure VLAN on node ports in the remote copy port group
on the remote system.
- Check to see whether connectivity between the local and
remote sites are restored.
- Restart the partnership.
