protocol connection lan on-oob-timeout
Configures out-of-band (OOB) LAN timeout settings.
Syntax
[no] protocol connection lan on-oob-timeout {drop all | drop same-inpath enable}
Parameters
drop all | Configures OOB connection shutdown on loss of connection. |
drop same-inpath enable | Configures an OOB connection shutdown on in-path loss of connection. |
Usage
Losing the OOB connection does not affect the optimized sessions, because the optimized sessions have a one-to-one mapping between the outer channel (the LAN-side TCP connection between the client and server, and the SteelHead) and the inner channel (the WAN-side TCP connection between the SteelHeads). The disadvantage to this approach is that the application does not notice when the peer is unavailable and the application might appear as if it is not working to the end user.
To address this, you can disconnect the inner and outer channels when the SteelHead loses its OOB connection with the protocol connection lan on-oob-timeout drop all command. For SteelHead appliances with multiple in-path interfaces, this command disconnects all the optimized sessions even if there are other OOB connections originating from other in-path interfaces.
To configure the SteelHead appliance to drop only the connections related to a specific in-path interface, use the protocol connection lan on-oob-timeout drop same-inpath enable command.
Example
amnesiac (config) # protocol connection lan on-oob-timeout drop all
amnesiac (config) # protocol connection lan on-oob-timeout drop same-inpath enable
