Fabric Advanced Hashing

Fabric Advanced Hashing is used to enable advanced fabric hashing on a chassis in GigaStream stack links and GigaSMART groups. The Fabric Advanced Hash option lets you select the criteria for sending matching flows to the same destination port within stack links.

The existing gigastream hashing can be applied only to tool/hybrid/circuit ports. Fabric advanced hashing hashes traffic based on the ipsrc, ipdst, protocol, ip6src, ip6dst. You can also select the various fields to configure hashing on stack links.

Fabric advanced hashing applies to the following modules:

■   GigaVUE‑HC1
■   GigaVUE‑HC2
■   GigaVUE-HC2+
■   GigaVUE‑HC3-v1
■   GigaVUE‑HC3-v2
■   GigaVUE-TA40
■   GigaVUE-TA100
■   GigaVUE-TA200

Fabric Advanced Hash can only be enabled or disabled while in Chassis Table View. To enable or disable Fabric Advanced Hashing, do the following:

1.   Select Chassis in the main navigation pane.
2. Switch the Chassis page to Table View.
3. Select the Box ID under Properties and select Actions.
4. Select the required Fabric Advanced Hash type from the drop-down.
5. The following options are available:
■   All: Selects all criteria
■   Default: Sets the fabric advanced hash algorithm to its default settings
■   None: Clears all fields from advanced hash
■   Fields: Allows you to select the required fields for advanced hash.

Note:  If Fabric Advanced Hash is already configured, click the Box-ID field to view the Fabric Advanced Hash configuration in a Quick View.
