You are troubleshooting a site-to-site VPN issue where the tunnel is not establishing. After issuing the debug crypto ipsec command on the headend router, you see
the following output.
What does this output suggest?
1d00h: IPSec (validate_proposal): transform proposal (port 3, trans 2, hmac_alg 2) not supported
1d00h: ISAKMP (0:2) : atts not acceptable. Next payload is 0 1d00h: ISAKMP (0:2) SA not acceptable
