Error Message
%ASA-6-602101: PMTU-D packet number bytes greater than effective mtu number dest_addr=dest_address , src_addr=source_address , prot=protocol
Explanation The Secure Firewall ASA sent an ICMP destination unreachable message and fragmentation is needed.
Recommended Action Make sure that the data is sent correctly.
602103
Error Message %ASA-6-602103: IPSEC: Received an ICMP Destination Unreachable from src_addr with suggested PMTU of rcvd_mtu; PMTU updated for
SA with peer peer_addr, SPI spi, tunnel name username, old PMTU old_mtu, new PMTU new_mtu.
Explanation The MTU of an SA was changed. When a packet is received for an IPsec tunnel, the corresponding SA is located and the MTU is updated based on the MTU suggested in the ICMP packet. If the suggested MTU is greater than 0 but less than 256, then the new MTU is set to 256. If the suggested MTU is 0, the old MTU is reduced by 256 or it is set to 256—whichever value is greater. If the suggested MTU is greater than 256, then the new MTU is set to the suggested value.
- src_addr—IP address of the PMTU sender
- rcvd_mtu—Suggested MTU received in the PMTU message
- peer_addr—IP address of the IPsec peer
- spi—IPsec Security Parameter Index

602104
Error Message %ASA-6-602104: IPSEC: Received an ICMP Destination Unreachable from src_addr , PMTU is unchanged because suggested PMTU of rcvd_mtu is equal to or greater than the current PMTU of curr_mtu , for SA with peer peer_addr , SPI spi , tunnel name username .
Explanation An ICMP message was received indicating that a packet sent over an IPsec tunnel exceeded the path MTU, and the suggested MTU was greater than or equal to the current MTU. Because the MTU value is already correct, no MTU adjustment is made. This may happen when multiple PMTU messages are received from different intermediate stations, and the MTU is adjusted before the current PMTU message is processed.
- src_addr—IP address of the PMTU sender
- rcvd_mtu—Suggested MTU received in the PMTU message
- curr_mtu—Current MTU associated with the IPsec tunnel
- peer_addr—IP address of the IPsec peer
