You can configure Gigamon Resiliency for inline protection on H Series nodes (GigaVUE-HC1, GigaVUE-HC2, and GigaVUE-HC3). Example 18 is an inline bypass solution for GRIP using TAP-HC1-G10040 modules on GigaVUE-HC1 with copper ports. The same instructions apply to GigaVUE-HC2 and GigaVUE-HC3.

Note: On the GigaVUE-HC2, the configuration steps will be the same as in this example, but the network ports and the TAP module will be different.

First, configure the GigaVUE-HC1 with the primary role, then configure the GigaVUE-HC1 with the secondary role. The configuration is the same (is synchronized) on both nodes, except for step 3, in which the protection role (primary or secondary) is specified.

Note that in this example, link fail propagation (LFP) is disabled to reduce inline network recovery time after failover. When a primary to secondary failover occurs and LFP is enabled for copper inline bypass links, network service recovery may take several seconds because of Ethernet link renegotiation. Optical links failover faster and typically recover service much faster. For inline networks where only one path is available, this is a consideration. When GRIP is deployed with high availability networks where a second path is present, it is a best practice to leave LFP enabled.

Configuring Primary Role GigaVUE-HC1

Step

Description

Command

1. Configure ports on the TAP-HC1-G10040 module as passive (in passive mode, relays are closed). Also configure ports, port type (inline-network).

(config) # port 1/3/g1..g8 params taptx passive
(config) # port 1/3/g1..g8 type inline-network

2. Configure stack port (for signaling port/link) and enable it.

(config) # port 1/1/x1 type stack
(config) # port 1/1/x1 params admin enable

3. Create the redundancy profile by giving it a name and configuring parameters for the redundancy profile such as the signaling port and protection role (primary).

(config) # redundancy-profile alias RP_001
(config redundancy-profile alias RP_001) # signaling-port 1/1/x1
(config redundancy-profile alias RP_001) # protection-role primary
(config redundancy-profile alias RP_001) # exit
(config) #

4. Configure inline network.

(config) # inline-network alias IN_001 pair net-a 1/3/g1 and net-b 1/3/g2

5. Associate the redundancy profile to the inline network. Also disable link fail propagation on the inline network.

(config) # inline-network alias IN_001 redundancy-profile RP_001
(config) # no inline-network alias IN_001 lfp enable

6. Configure inline tool ports, port type (inline-tool), and administratively enable them.

(config) # port 1/1/x11 type inline-tool
(config) # port 1/1/x11 params admin enable

(config) # port 1/1/x12 type inline-tool
(config) # port 1/1/x12 params admin enable

7. Configure inline tool and failover action. Then enable inline tool.

(config) # inline-tool alias IT_001 pair tool-a 1/1/x11 and tool-b 1/1/x12
(config) # inline-tool alias IT_001 failover-action network-bypass
(config) # inline-tool alias IT_001 enable

8. Configure map passall, from inline network to inline tool.

(config) # map-passall alias INtoIT
(config map-passall alias INtoIT) # from IN_001
(config map-passall alias INtoIT) # to IT_001
(config map-passall alias INtoIT) # exit
(config) #

9. Configure the path of the traffic to inline tool.

(config) # inline-network alias IN_001 traffic-path to-inline-tool
