fabric advanced-hash
Required Command-Line Mode = Configure
Use the fabric advanced-hash command to select the criteria for advanced-hashing behavior on stack GigaStreams and GigaSMART groups. You can configure fabric-advanced hash at the chassis level.
The fabric advanced-hash command is supported on the following platforms:
GigaVUE‑HC1 |
GigaVUE‑HC2 |
GigaVUE-HC2+ |
GigaVUE‑HC3-v1 |
GigaVUE‑HC3-v2 |
GigaVUE-TA40 |
GigaVUE-TA100 |
GigaVUE-TA200 |
GigaVUE‑TA25 |
The fabric advanced-hash command has the following syntax:

The following table describes the arguments for the fabric advanced-hash command:
Argument |
Description |
||||||||||||||||||||||||||||||||||||||||||||||||
box-id |
Identifies the chassis to which the advanced-hash algorithm will apply. (config) # fabric advanced-hash box-id 12 |
||||||||||||||||||||||||||||||||||||||||||||||||
all |
Enables all hash criteria fields, including Layer 2, Layer 3, and Layer 4 fields. Note: When both Layer 3 (IPv4 or IPv6) and Layer 2 (MAC) fields are enabled for a given GigaStream and there is a mix of Layer 3 and Layer 2 packets, Layer 3 will take precedence. The incremental Layer 3 packets will hash; the incremental Layer 2 packets will not hash. (config) # fabric advanced-hash all |
||||||||||||||||||||||||||||||||||||||||||||||||
default |
Sets the advanced-hash algorithm to its default settings. By default, the advanced-hash algorithm includes source/destination IPv4/IPv6 addresses and ports (ipsrc, ipdst, ip6src, ip6dst, protocol). For example: (config) # fabric advanced-hash default |
||||||||||||||||||||||||||||||||||||||||||||||||
fields |
(config) # fabric advanced-hash fields <fields> Specifies the hash criteria. Includes the following options:
Note: Layer 2 hash criteria (ethertype, macdst, and macsrc) are only honored for Layer 2 packets. They are not used to hash TCP/IP packets. ipsrc, ipdst, ip6src, and ip6dst fields inside an MPLS tunnel can also be used for hashing across GigaStream ports. GTP TEID can also be used for hashing across GigaStream ports. ingress port can also be used for hashing across GigaStream ports. |
||||||||||||||||||||||||||||||||||||||||||||||||
none |
Clears all fields from the advanced hash. For example: (config) # fabric advanced-hash box-id 12 none |
