Would just like to confirm the meaning of the "#send errors" in the show crypto ipsec sa peer <ip> command output.
Trying to troubleshoot a L2L VPN connection. For some reason the customer isnt able to access the network behind our firewall. The actual L2L VPN connection has worked before now for some reason doesnt.
I can get the tunnel up by using icmp with the source address from a range originally assigned for the connection. The show crypto session remote <ip> shows the tunnel briefly in UP-IDLE state. So seems the tunnel configuration is fine between the two peers?
Though my actual question is what are the "#send errors" output result of spesifically? When I use icmp from our side to their firewall i dont see increase in the hitcount for encapsulated packets but see #send errors. Still the tunnel goes UP-IDLE state after sending the icmp messages.
I tried to find an explanation for all the information the show crypto ipsec sa peer <ip> commands output gives but couldnt find any.
Any help would be appriciated
