I'm losing packets on my switches between our voip phones when using or when not using and only pinging the phones.
The phones are currently in vlan 2, this vlan has rspan on for voice recording. The source switches have trunk ports and these connect to the phone and the pc's connect to the network via the phones.
All the source ports have the following config:
switchport trunk encapsulation dot1q
switchport mode trunk
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
mls qos trust dscp
auto qos voip trust
no mdix auto
The rspan configuration on the source switches is:
monitor session 1 source vlan 2
monitor session 1 destination remote vlan 50
On the destination switch the config is:
monitor session 1 destination interface Gi1/0/2
monitor session 1 source remote vlan 50
The Gi1/0/2 interface has the following config:
switchport access vlan 21
switchport mode access
no mdix auto
I can't see why I would lose packets when even just pinging the phones. The destination switch is running eigrp and routing betweent the vlan's. If I ping from another vlan to vlan 2(i.e the phone vlan) I lose packets but if I ping devices between any vlan that doesn't have RSPAN capturing data I don't lose any packets.
Just to let you know the phones are like mini switches and they tag their own traffic into vlan 2 and the pc data into any defined vlan.
Can someone please shed some light on to this and how I can resolve it.
Thanks in advance
