Connecting the Switch to the Network
3 - 8
Entering the Private Subnet
Enter the private subnet and VLAN of the failed switch, as well as the
VLAN for the private metalog subnet. The VLANs must be unique in the
network, shared only among the ARX devices in the RON. The defaults
(1002 and 1003) may be sufficient for the installation. See the following
example.
...
The
switch's internal subnet requires an IP address and mask.
7. Enter the switch's private IP address
in the format nnn.nnn.nnn.nnn.(default=169.254.6.0) #
169.254.100.0
8. Enter the switch's private subnet mask
in the format nnn.nnn.nnn.nnn.(default=255.255.255.0) # <Enter>
The private subnet VLAN is used externally for redundancy traffic.
Be sure this value does not conflict with existing VLAN IDs.
9. Enter the switch's private subnet VLAN
in the format integer [1 ‐ 4095].(default=1002) # 1008 <Enter>
The private subnet metalog VLAN is used for storing file ‐ change
logs on battery ‐ backed NVRAM, possibly on a redundant peer.
Be sure this value does not conflict with existing VLAN IDs.
10. Enter the switch's private subnet metalog VLAN
in the format integer [1 ‐ 4095].(default=1003) # 1009 <Enter>
Finding the UUID of the Failed Switch
When a switch imports storage from backend file servers, it marks each
share with its UUID (Universally-Unique ID). A replacement switch must
use the same UUID or it will reject all shares imported by its predecessor.
Also, you must set the UUID if the switch is brought back to its factory
defaults. A
Manufacturing Installation by F5 personnel resets the switch
and its UUID.
The UUID appears at the top of the output of a show running-config
command as in the following example from a switch named bstnA . The
UUID is highlighted in bold.

If the failed switch was a member of a RON, you can enter the show ron
command from any other RON member. The output from this command
shows the UUID even if the chassis is no longer online.
