VLANS

Is it OK to have a trunk (tagged link) and an untagged (access link) between two HPE 5412 switches?

Re: VLANS

Hi,

What is the purpose for configuring trunk and access on conencting two devices?

Trunk will carry the multiple VLAN traffic but access will carry only one particular vlan traffic.

As per my opinion either trunk wil work or access will work.

Both toghether will not work.

Thanks!

Re: VLANS

It clearly depends on how you have configured (M)STP on both peers...

Re: VLANS

I am not sure why the access port and trunk are configured together.

I ran into this senario on a new job and have never worked with hp before so I figured I'd ask.

Vlan 1 = native vlan

Vlan 50 = Internet Traffic

Vlan 256 = DMZ

I know if we pull the cable with vlan 50 we loose Interntet connectivity.  

10.1.0.3 is physically connected to the FW with 3 fibre cables.  

Vlan 50 - Inside

Vlan 212 - Outside

Vlan 256 DMZ

10.1.0.3 is also physically connected to the ISP vlan through 212

Basicaly 10.1.0.3 has all traffic passing through it and is being used as a circuit with no routing.  All routing is done on the 10.1.0.1 switch. 

I would think to move 10.1.0.3 out of the picture and behind the FW but they want to have outside lines configured for testing (no traffic passing though the firewall)

Re: VLANS

STP is only configured on 10.1.0.1

If we turn in on 10.1.0.3 we get a blocked port.

10.1.0.3 has connections to both the FW and the ISP and is basicaly a "buffer"
