SP Switch Router Adapter card maint commands

Display switch route table - maint 189 2

The SP Switch sends the SP Switch Router Adapter card routes for the active nodes. The SP Switch Router Adapter card receives these routes and appends the hex addresses to packets going to the target node on the SP Switch (identified by Node_ID.

If switch route table addresses do not match the SP Switch Router Adapter card entries, the gr.console log displays a series of “Switch route not found” messages.

“Switch route not found”

The message is sent during ARP processing when a searched-for entry is not found in the switch route table. The table mismatch is due either to a configuration error or to corrupted packets coming from the the SP Switch. Here is an example of the message:

Switch route not found, node=33386

The node= value is the SP Switch node number in decimal. If the node= value is low, the cause is probably a configuration error. With ARP mode set to 0, the card’s ARP table does not have a switch route from the switch to match the destination IP address/netmask for an ARP to be created. The message also appears when the SP Switch Router Adapter media card receives an ARP from the switch, but the hardware address in the ARP packet does not match any switch routes in the switch route table. In either case, the message means the switch route table that the SP Switch Router Adapter card receives from the SP Switch is not matching up with addresses that are attempting to flow through the media card.

If the node= value is high, as in the example, it is likely due to corrupted packets coming from the SP Switch.
