IKE (Phase 1) Statistics
This table provides IPSec Phase 1 (IKE: Internet Key Exchange) global statistics. During IPSec Phase 1
(IKE), the two peers establish control tunnels through which they negotiate Security Associations.
Active Tunnels
The number of currently active IKE control tunnels, both for LAN-to-LAN connections and remote
access.
Total Tunnels
The cumulative total of all currently and previously active IKE control tunnels, both for LAN-to-LAN
connections and remote access.
Received Bytes
The cumulative total of bytes (octets) received by all currently and previously active IKE tunnels.
Sent Bytes
The cumulative total of bytes (octets) sent by all currently and previously active IKE tunnels.
Received Packets
The cumulative total of packets received by all currently and previously active IKE tunnels.
Sent Packets
The cumulative total of packets sent by all currently and previously active IKE tunnels.
Received Packets Dropped
The cumulative total of packets that were dropped during receive processing by all currently and
previously active IKE tunnels. If there is a problem with the content of a packet—such as hash failure,
parsing error, or encryption failure—received in Phase 1 or the negotiation of Phase 2, the system drops
the packet. This number should be zero or very small; if not, check for misconfiguration.
Sent Packets Dropped
The cumulative total of packets that were dropped during send processing by all currently and previously
active IKE tunnels. This number should be zero; if not, check for a network problem, check the event
log for an internal subsystem failure, or contact Cisco support.
