Description: Event GW.35 When the router went to send a packet to a given host, the network interface it had been told to send the packet over to was not up. The output discard counter for that interface was incremented, and the packet was returned to the protocol forwarder for attention. Usually, next-hop-host will be the MAC layer address of the next hop router or host that this packet is being sent to. The format of this MAC address depends on the network type. If next-hop-host starts with an @ (at-sign), then that network does not provide a formatted display of MAC addresses, and the following number is the hex address in router memory that the next hop host address is stored at.
