Unhappy Es 470-48t-pwr

Hi Guys,

I have a site, in which 3 ES 470 are stacked . I have more than five applications like, VoIP, Data-Admin, Guest-Internet, IPTV, Wireless Acess pionts and CCTV (security cameras) running on these switches . Well few months after the installation the vlans handling the CCTV, failed to give pictures on the screens. When I shifted the CCTV vlan to a stand alone switch, it works, but not on the stack switches.
I dont think there is any problem with the stacking. Or should I reconfigure the stacked switches from the scrach. Well I would be grateful, if someone could help me to sort out this problem, as it has become a serious issue .

Regards
Gibbs Justin

Hi Justin,

Can you ping the machines in that subnet if you connect your laptop to the same subnet?

Did you check the settings on the VLAN?

Did you check the default VLAN ID? (very important one!)

cheers

Bas

Hi Bas,

Well these are answers for the questions,

1. Can you ping the machines in that subnet if you connect your laptop to the same subnet?
Ans: Yes, I can ping to the machines, from my laptop to that machines. ( except the gateway of the machines )

2. Did you check the settings on the VLAN?
Ans: Yeah, the port belongs to the CCTV Vlan.

3. Did you check the default VLAN ID? (very important one!)
Ans: Yeah, pvid - CCTV vlan
port priority - 5

Is there any other settings which I should do on the Vlan side. Hoping for your reply.

cheers
Gibbs
