Data Center Migration from Hongkong to Singapore

[_Mudit]

Pre-checks on migrations:

• Make sure that all switches and APs added on cloud should be operational.
• Make sure to whitelist below IPs/FQDNs on your firewall outbound rules:

1.            IP range: 34.87.82.64 through 34.87.82.95, ports: tcp 443 & 22
2.            FQDN: ap-registrar.ruckuswireless.com, port: tcp 443
3.            FQDN: sw-registrar.ruckuswireless.com, port: tcp 443
4.            FQDN: ocsp.comodoca.com, port: tcp 443 & 80
5.            FQDN: ocsp.entrust.net, port: tcp 443 & 80
6.            FQDN: device.asia.ruckus.cloud, port: tcp 443 & 22
7.            FQDN: storage.googleapis.com, port: tcp 443

Post migration connectivity checkpoints and troubleshooting before contacting Ruckus Support:

AP Troubleshooting:

• Connect laptop to a switch and same subnet as APs. Ping device.asia.ruckus.cloud, and please check if the resolved IP is in range: 34.87.82.64 through 34.87.82.95.

• If the resolved IP is outside the mentioned range (34.87.82.64 through 34.87.82.95), make sure to flush DNS cached entries from DNS server. Now try to resolve “device.asia.ruckus.cloud” and validate that IP resolution is within the specified IP range.

$ curl -XGET “https://device.asia.ruckus.cloud”

On MacOS, a success response would be:

curl: (56) LibreSSL SSL_read: LibreSSL/3.3.6: error:1404C45C:SSL routines:ST_OK:reason(1116), errno 0

On Windows PC, a success response would be:

     curl : (56) Send Failure: Connection was aborted

• Check reachability to https://device.asia.ruckus.cloud using the command below.

• Feel free to contact Ruckus Support, if all the troubleshooting steps are exhausted.

ICX Switch Troubleshooting:

• For Switches on version 9010e and 9010f kindly reboot the switches to clear DNS cached entries.

• Switches on version 9.0.10h_cd2 and 10.0.10b (for ICX 8200 switches) will not require a reboot to get connected to the new DC.

• Run “show sz status” from switch CLI and check SWR (Switch Registrar) IP has updated new IP range from 34.87.82.64 through 34.87.82.95.

• If the IP address is outside the above range run below commands:

1. device(config)# manager disable
2. device(config)# no manager disable
3. device# manager registrar-query-restart
4. device# show manager status

• Feel free to contact Ruckus support if above steps does not help.

Note that, switch disconnection from cloud doesn’t impact the production due to data center migration.
