For subordinate CA authentication, the full chain of CA certificates ending in a self-signed CA is

required because the CA chain is needed for certificate verification as well as for PKCS#12 format
export.
Configuring Certificate Revocation Checking Methods
During security exchanges with a client (for example, an IKE peer or SSH user), the MDS switch
performs the certificate verification of the peer certificate sent by the client and the verification process
may involve certificate revocation status checking.
You can use different methods for checking for revoked sender certificates. You can configure the switch
to check the CRL downloaded from the CA (see the
can use OSCP if it is supported in your network, or both. Downloading the CRL and checking locally
does not generate traffic in your network. However, certificates can be revoked between downloads and
your switch would not be aware of the revocation. OCSP provides the means to check the current CRL
on the CA. However, OCSP can generate network traffic that can impact network efficiency. Using both
local CRL checking and OCSP provides the most secure method for checking for revoked certificates.
