Adding a non cisco switch to a network port

I need to add a switch to a network port to allow for around 10 connections. I thought I needed to make the port a trunk port (switchport mode trunk) and to add dot1q encapsulation is this correct?

Any help with the correct commands would be very helpful thanks.

The network is based on a 6509 core and 9 3750 stacks.

A trunk is not required here.

Simply configure the cisco-side as access port:

swi mo acc

swi acc vlan ..

Thanks Leo

The current config for the port is:

switchport access vlan #

switchport mode access

switchport voice vlan #

switchport port-security maximum 2

switchport port-security

switchport port-security aging time 2

switchport port-security violation restrict

switchport port-security aging type inactivity

auto qos voip cisco-phone

macro description cisco-phone

spanning-tree portfast

spanning-tree bpduguard enable

Will this allow for the ten connections or will I need to increase the port security max to 10 or maybe 11 to be sure?

Well, you do not want port security here because it limits the number of hosts that can be connected. (two in the above case)

Also, remove the bpduguard because the switch that is to be attached will send bpdu packets.

I suppose there is no cisco-phone connected to the port?

In that case; remove the voice vlan as well. This is what's needed:

no switchport voice vlan #

no switchport port-security

no spanning-tree bpduguard enable

Hi Chris,

Yes, you need to add:

switchport

switchport trunk encapsulation dot1q

switchport trunk allowed vlan xx, xx, xx

switchport mode trunk

Hi,

If the switch you are connecting to Cisco has any VLANs configured in it ,then you need to connect it to a trunk port. Otherwise it can be connected to access port
