GigaSMART De-duplication

GigaSMART de-duplication detects duplicates of the following types:

■   IPv4 packets
■   IPv6 packets
■   non-IP packets (including non-IPv4 and non-IPv6 packets)

Duplicates are packets in which the fields (including the headers and payload) are the same, with the exception of some field such as Time-to-Live (TTL). For example, if two packets are identical except for TTL, they will be counted as duplicates.

GigaSMART De-duplication Example

This example shows the configuration steps for a de-duplication operation in which the GigaSMART application drops duplicate packets.

Step

Description

Command
1.    

Configure a GigaSMART group and associate it with a GigaSMART engine port.

(config) # gsgroup alias gs2port1 port-list 2/1/e1
2.  

Configure parameters on the GigaSMART group.

(config) # gsparams gsgroup gs2port1 dedup-action drop

(config) # gsparams gsgroup gs2port1 dedup-ip-tos ignore

(config) # gsparams gsgroup gs2port1 dedup-tcp-seq ignore

(config) # gsparams gsgroup gs2port1 dedup-vlan ignore

(config) # gsparams gsgroup gs2port1 dedup-timer 55000
3.  

Configure the GigaSMART operation for de-duplication and assign it to the GigaSMART group.

(config) # gsop alias testdedup dedup set port-list gs2port1
4.  

Create a map.

(config) # map alias testingdedup

(config map alias testingdedup) # type regular byRule

(config map alias testingdedup) # use gsop testdedup

(config map alias testingdedup) # from 2/2/x4,2/2/x6

(config map alias testingdedup) # to 2/2/x9

(config map alias testingdedup) # rule add pass portsrc 443 bidir

(config map alias testingdedup) # exit

(config) #
5.  

Display the configuration and statistics for this example.

(config) # show gsgroup

(config) # show gsop

(config) # show map

(config) # show gsop stats

(config) # show port stats
