How to forward vlan for ip telephony?

Question

SIP

Tell me how to forward Vlan 5 to port FE 0/22.
On all ports where vlan5 is needed, I registered
interface FastEthernet
switchport access vlan 5
switchport mode access
BUT the link does not rise on ports FE 0/3 and FE 0/23.
Help forward

Answer 1

Not raising the link is most likely a physical problem and does not depend on the Wealan, the only thing is that with such a connection as in the picture, you could catch the ring with crooked settings and the link turned off. Give a trunk link between the ciscos, so it will be more beautiful and without the ability to make a loop with a crooked configuration.

Answer 2

do aggregation between switches
Link Aggregation

Answer 3

I agree with rostel. First, fix the link between the switches, and at the same time check the VTP on them.
On the top 3550:

int ra fa0/2 - 3
description -=I=- Link to 3550 -=I=-
 switchport mode trunk
 channel-group 1 mode active

interface Port-channel1
 description -=I=- Link to 3550 -=I=-
 switchport mode trunk

On the lower 3550:

int ra fa0/22 - 23
description -=I=- Link to 3550 -=I=-
 switchport mode trunk
 channel-group 1 mode active

interface Port-channel1
 description -=I=- Link to 3550 -=I=-
 switchport mode trunk

Further, if you have an IP phone with a port for a computer plugged into fa0 / 22:

interface fa0/22
 switchport access vlan <рабочий VLAN компьютера воткнутого в телефон>
 switchport mode access
 switchport nonegotiate
 switchport voice vlan 5
 spanning-tree portfast

If you have only an IP phone plugged into fa0/22:

interface fa0/22
 switchport access vlan 5
 switchport mode access
 switchport nonegotiate
 spanning-tree portfast
