Changes to stack-port and stack-trunk Configuration
Beginning with FastIron 08.0.90, using the
stack-port and
stack-trunk commands to configure stacking ports and trunks eliminates the following restrictions
that were present in previous configuration methods.
- A stacking trunk had to be built on top of a stacking port. Without
stack-portconfiguration, you could not addstack-trunkconfiguration. Both thestack-portand thestack-trunkconfiguration represented thestack-trunk. - In releases prior to FastIron 08.0.90, the command
no stack-trunkchanged a stacking trunk to its underlying stack-port; it did not remove all ports from the stacking trunk. - A
stack-portconfiguration could contain one or two stack-ports. If you re-entered thestack-portcommand with only one of the original two ports, the other port was removed. - To configure stacking ports or stacking trunks that did not use the factory-set stacking
ports, you first had to configure different default ports (choosing from those available)
using the
stack default-portscommand.
General Comparison of the New and Old Behaviors in Configuring Stacking Ports and Trunks
The following table provides a side-by-side comparison of stacking port and stacking trunk configuration basics in FastIron 08.0.90 (New behavior) and prior releases (Old behavior). The new behavior uses one command per stack-port or stack-trunk.
General Comparison of Old and New Behavior
| Objective | New Behavior | Old Behavior 1 |
|---|---|---|
| 1 port | stack-port 1/2/1 | stack-port 1/2/1 |
| 2 ports |
stack-port 1/2/1 stack-port 1/2/4 |
stack-port 1/2/1 1/2/4 |
| 1 trunk | stack-trunk 1/2/1 to 1/2/3 |
stack-port 1/2/1 stack-trunk 1/2/1 to 1/2/3 |
| 1 port and 1 trunk |
stack-port 1/2/4 stack-trunk 1/2/1 to 1/2/3 |
stack-port 1/2/1 1/2/4 stack-trunk 1/2/1 to 1/2/3 |
| 2 trunks |
stack-trunk 1/2/1 to 1/2/3 stack-trunk 1/2/4 to 1/2/5 |
stack-port 1/2/1 1/2/4 stack-trunk 1/2/1 to 1/2/3 stack-trunk 1/2/4 to 1/2/5 |
Comparison of Configuration Changes that Use Non-factory valid-stack-port Sets
The following table provides a side-by-side comparison of new and old configuration
command behaviors for stack configurations that use stack-ports other than the factory-set
default ports. In the table, an ICX 7750 stack serves as the example, and configuration
changes use stack-ports other than the factory-set combination (ports 1/2/1 and 1/2/4).
The new behavior does not require you to use the
default-ports command.
Comparison of Commands that Use valid-stack-ports Other than the Factory-set Default Stacking Ports
Comparison of Common Configuration Procedures Using Factory-set Default Stacking Ports
The following series of tables provide side-by-side comparisons of new and old configuration behaviors required for standard stack configuration procedures when factory-set default stacking ports are used. The examples reference ICX 7750 stack configuration, for which factory-set default stacking ports are 1/2/1 and 1/2/4.
The old behavior sometimes required multiple commands to add or delete one stack-port or stack-trunk and sometimes needed only one command to add or delete two stack-ports or stack-trunks. In contrast, the new behavior always adds or deletes a stack-port or stack-trunk with one command.
Removing a Stacking Port
Changing a Stacking Port to a Stacking Trunk
Changing a Stacking Trunk to a Stacking Port
Adding a Stacking Trunk
stack-port command adds a stacking port. The second command,
stack-trunk, changes the stacking port just added to a stacking trunk.
Completely Removing a Stacking Trunk
no stack-trunk, changes the trunk to a stacking port. The second command,
no stack-port, is required to remove the trunk completely. Another option is to enter the command
no stack-port 1/2/1, which removes both the
stack-trunk and the
stack-port configuration.
Changing the Sole Stacking Port or Trunk to Another Stacking Port or Trunk
Removing a Stacking Trunk to Add a New Trunk that Uses Different valid-stack-ports
Changing Two Stacking Ports to Ports in a Different valid-stack-port Set
