VDX/VCS discovery
3
VCS devices use the following to determine reachability:
• Reachable — The VDX/VCS product is online and is accessible by ICMP, Netconf, and SNMP;
therefore, it is reachable.
• Degraded Link — The VDX/VCS product is not accessible by one of the following: ICMP, Netconf,
or SNMP.
• Not Reachable — The VDX/VCS product is offline and is not accessible by any of the following:
ICMP, Netconf, and SNMP.
The following sections detail the VDX/VCS discovery behavior.
Network OS discovery IP address format
You can discover Network OS devices using an IPv4 or IPv6 address. To configure the preferred IP
format for the Management application server to connect with Network OS devices, refer to
“Configuring the preferred IP format” on page 216.
During discovery, if the product has both an IPv4 and IPv6 address, the Management server uses
the preferred address. If a product does not have the preferred address type, the Management
server uses the other IP type. If the Management application is not IPv6 capable, the Management
application cannot discover products with an IPv6 address directly (as a seed switch). The
Management application can discover products with an IPv6 address indirectly when the seed
switch has an IPv4 address.
VCS in-band management interface discovery
You can discover VCS devices using in-band or out-of-band management interfaces. If you
configure a VCS cluster member with both in-band and out-of-band management interfaces, the
Management application uses the in-band management interface to fetch device data and the
member switch displays the in-band management interface IP address in the application. If you do
not configure an in-band management interface, the Management application uses the
out-of-band management interface for data collection.
Mapping VCS in-band management
For VCS device in-band management, you must map the VCS device WWN to the in-band
management interface IP address in the DeviceWWNToIPMap text file; otherwise, discovery fails.
1. Open the in-band mapping file (DeviceWWNToIPMap.txt) in a text editor (such as, Notepad).
The DeviceWWNToIPMap.txt file is located in the Install_Home/conf/discovery/ip directory.
2. Enter the in-band IP addresses you want to include in discovery.
You must use the following format: the device WWN, followed by a space, and then the valid
in-band IP address.
Example
10:00:00:05:33:51:62:42 172.26.20.10
# DeviceWWNToIPMap.txt
# In-Band Management IP address should be mapped to Device WWN.
# The format consists of two columns per line, separated by white space.
# Each column consists of Device WWN followed by white space and followed by
In-band IP address
