Multiple port binding
2
To simplify an existing configuration that uses port aliases, you can manually convert that
configuration to the direct binding method to reduce the size of SLB configurations. If you choose to
use the direct method, you must first remove all alias port bindings and reload your configuration.
Direct binding of multiple ports
Direct binding of multiple ports enables you to associate a real server TCP or UDP port with multiple
virtual TCP or UDP ports.
Binding a real server port to multiple VIPs
To bind one real server port (rs1) to multiple VIPs (vs1 and vs2), complete the following steps:
1. Create a real server with one port.
Virtual ADX(config)#server real rs1 10.0.0.1
Virtual ADX(config-rs-rs1)#port http
2. Create a virtual server.
Virtual ADX(config)#server virtual vs1 10.0.0.101
3. Create an HTTP port on the virtual server.
Virtual ADX(config-vs-vs1)#port http
4. Bind the real port on the real server to the HTTP port on the virtual server.
Virtual ADX(config-vs-vs1)#bind http rs1 http
5. Repeat the steps 2 through 4 for each additional virtual server.
Virtual ADX(config)#server virtual vs2 10.0.0.102
Virtual ADX(config-vs-vs2)#port http
Virtual ADX(config-vs-vs2)#bind http rs1 http
.
Configuration rules
Although both direct binding of multiple ports and port binding of multiple ports via port aliases are
supported by the Brocade Virtual ADX, the two configurations cannot co-exist for the same real port
or virtual port.
A real server port cannot be bound to a virtual port if any of the following conditions are met:
•
The real port is already bound to another virtual port as an alias port.
•
The virtual port has been bound to an alias port.
•
The virtual port is configured for stateless or stateless fragmentation support. For more
information, see
“Fragmentation support in the stateless mode”
•
The virtual port is configured for persistent hashing. For more information, see
When a real port is bound to multiple virtual ports, the following configurations are not allowed:
•
A virtual port with a multiple port binding cannot be bound as an alias port.
•
The real port cannot be bound as an alias port or use another port as an alias port.
•
The virtual port cannot be configured for stateless or stateless fragmentation support.
•
The virtual port cannot be configured for persistent hashing.
