Hello,
I'm new to Cisco Small Business Switches, and facing Phone reboot problem
Deploying Avaya SIP 9608 Phones and a PC cascaded to these phones on
Cisco Small Business Switch: SG250-50P with Firmware Version: 2.3.5.63
Based on some of the community discussions,
1. Administrative Auto smartport: Disabled
2. Dynamic Voice VLAN: Disabled
3. Auto Voice VLAN: Disabled
4. Applied "no macro auto smartport" on all these switch ports.
5. Switch port is configured as Trunk and Data VLAN 505 is native and Voice VLAN 22 is allows and tagged over the trunk.
6. There are 8 standalone phones connected to access ports on the same switch and member of VLAN 22
Phones and PCs got IP addresses from the respective DHCP servers running Fortigate firewall, phones got registered to the Avaya Cloud CM instance properly.
Everything worked for 4-5 hours and then all the phones got rebooted(including standalone phones)
