debug ip gre keepalive
Syntax: [no] debug ip gre keepalive
This command activates the Generic Routing Encapsulation (GRE) keepalive debugging.
Brocade# debug ip gre keepalive
GRE_MP: Keepalive Bring DOWN GRE Tunnel
GRE_MP: Keepalive Bring UP GRE on Tunnel 11 - port is 2/1/2
GRE_MP: RX Keepalive packet on tnnl 11 src 10.22.33.254, dst 10.22.33.252
GRE_MP: TX Keepalive packet on tnnl 11 we need to find outgoing port
GRE_MP: TX Keepalive packet on tnnl 11 - outgoing_port is 2/1/2 with mac
0000.00bb.ef40 vlan 2
GRE_MP_KEEPALIVE: NO FREE BUFFER AVAILABLE
GRE_MP: For Tunnel 11, Keepalive timeout after 3 seconds
GRE_MP: For Tunnel 11, stop keep-alive
GRE_MP: For Tunnel 11, start keep-alive
GRE_MP: enqueue Keepalive packet on tunnel 11 at index 23
GRE_MP: dequeue Keepalive packet on tunnel 11 at index 23
