Dear All,
We have two sg300-52 managed switch connected via gi 52 with trunk ports. One of these (switchA) connected (via gi51) with an other cisco sf300-24p (switchVOIP) managed switch, which preconfigured and I don't know the configuration. This sf300 is used for voip. There is a fourth unmanaged 3com switch (switch3COM) with connection to the other sg300 (switchB).
There are four vlan in switchA and switchB:
Vlan1 -> the default vlan1, connected to switch3COM (and it seems to be good)
Vlan10 -> office net
Vlan5 -> voip
vlan105->public
switch3COM --} VLAN1 {---switchB --- gi52 } TRUNK allowed 1,5,10,105 {gi52----switchA ---gi51 Access port VLAN 5}---{swicthVOIP
My problem is the connection between switchA and switchVOIP.
The switchVOIP is in 'default mode', the contact person said they don't configure it, and leaving everythink defult. So I think it use its default vlan1 on its every ports. However the phones work perfectly, on switchA I can see the:
CDP-W-NATIVE-VLAN-MISMATCH on interface gi 51.
On the switchA I configured the gi51 (to the switchVOIP) access mode.
show interfaces switchport gi 51 =>
PortMode:access
Ingress Filtering:true
Acceptable Frame Type; adminAll
Ingress Untagged VLAN (NATIVE): 5
Port is memeber in:
Vlan 5
Egress rule:untagged
I would like every packet leaving switchVOIP to be injected in my switchA VLAN5, and as I know this should be done by
Ingress Untagged VLAN (NATIVE): 5
Is there any way to get rid of this mismatch messages?
Thank you very much.
