AvailabilityGuard™ uses the following methods to collect configuration data regarding Cisco MDS fabric switches:
- Querying Cisco SAN switches directly.
- Querying Cisco Data Center Network Manager (DCNM) - recommended.
Direct Cisco SAN Switch Scanning
When using a direct switch scan, AvailabilityGuard™ opens an SSH session to the Cisco MDS switch and executes read-only Cisco MDS CLI show commands.
To scan a Cisco SAN switch, you should make the following preparations:
- Obtain the Switch Name or IP address - if not automatically discovered.
- Obtain a Switch user account with permission to run show commands.
- Verify that IP connectivity through SSH (default is port 22) is available between the AvailabilityGuard™ collector server and the Cisco MDS Switch.
Cisco Data Center Network Manager (DCNM)
When using Cisco Data Center Network Manager (DCNM), AvailabilityGuard collects configuration data from DCNM by running read-only Web Services soap queries.
To scan DCNM, you should make the following preparations:
- Obtain the DCNM server name or IP address.
- Obtain a DCNM user name and password.
- Verify that IP connectivity through SOAP (port 443) is available between the AvailabilityGuard application collector and the DCNM server.
- When scanning switches directly, AvailabilityGuard™ will automatically detect other Cisco switches in the same fabric. There's no need to manually define each Switch.
- It is possible to configure AvailabilityGuard™ to automatically add newly detected switches to the scan. For this reason, it is recommended to use a standard credential set for scanning Cisco SAN switches.
