Figure 128: IPsec Status
The “IPsec Status” button produces a window of text similar to that of the above
figure (except that line numbers have been inserted for purposes of illustration).
The first group (lines 1-5) describes configured interfaces.
The second group (lines 7-17) describes ESP capabilities. In this group we can see
encryption capabilities (lines 7-13) and authentication capabilities (lines 14-17). At
least one set of values must match between the left- and right-hand side VPN devices.
This is also frequently referred to as the Phase 2 parameters, because the data
encryption process is the second and final thing to occur in establishing a VPN.
The third group (lines 18-28) describes IKE capabilities and defines the various
encrypted key exchange algorithms and their parameters. At least one set of values
must match between the left- and right-hand side VPN devices. This is also frequently
referred to as the Phase 1 parameters, because the key exchange process is the first
thing to occur in establishing a VPN.
