Dear lowfell, Add these to your configuration interface Port-channel128 description switchport trunk encapsulation dot1q <--- Add tagging if you want your VLANS to be tagged !! switchport trunk allowed vlan 2,201,208,253-255,705 switchport mode trunk interface GigabitEthernet7/0/1 description switchport trunk encapsulation dot1q <--- Add tagging if you want your VLANS to be tagged !! switchport trunk allowed vlan 2,201,208,253-255,705 switchport mode trunk channel-protocol lacp <--- Define channel protocol i.e LACP or PAgP channel-group 128 mode active ! interface GigabitEthernet7/0/2 description switchport trunk encapsulation dot1q <--- Add tagging if you want your VLANS to be tagged !! switchport trunk allowed vlan 2,201,208,253-255,705 switchport mode trunk channel-protocol lacp <--- Define channel protocol i.e LACP or PAgP channel-group 128 mode active HTH Regards, Talha

Yes you are right manual configs are the only option as i have worked on unify (Siemens) systems from Openscape 4000 to X8 and X5. Non of these systems have the option 43 available. Regards, Talha

If its possible for you setup a DHCP server which can do the job quite well enough for voice vlans and data as well. Regards, Talha

@Deepak kumar I knew about these DHCP options but in my scenario there was no option of DHCP server as client insisted to stick on manual configs. Regards, Talha

@Deepak kumar It won't be easy as you have to configure each phone manually but that is the only way out. I have came across this scenario at a financial institution which consist of thousand phones almost and each floor has different vlan for voice. But its been done in stages not at once so i don't have any overhead to complete the task at once. Regards, Talha

Dear Karinatan, If you have 9 voice vlans than all you have to do is enter voice gateway ip address i.e your UNIFY system IP while configuring your phones, so that these phones gets registered on UNIFY server and start working. In IP phones you have option like this IP add : 192.168.X.X Mask : 255.255.255.0 Subnet GW: 192.168.X.X VOIP Gateway : 192.168.X.X Once you enter these phones will register and start working Regards, Talha

Hi karinatan, Firstly enable DHCP for IP Phones in Openscape business, secondly reserve a small range of IP addresses while configuring DHCP in your openscape business system. Now follow these steps. #int vlan 10 #ip add 192.168.0.5 255.255.255.0 <--- (define your voice subnet accordingly) #ip helper-address 192.168.0.1 <--- (Ip address of your unify openscape LAN segment) #description VOICE #end #int gig 0/1 #switchport mode access #switchport access vlan 5 <-- Vlan 5 represents your data vlan here for example) #switchport voice vlan 10 <-- Vlan 10 represents your voice vlan here for example) #end In this manner your phones and PC's will work on same switchport, secondly you won't be needing QOS as they will work fine without any hassle.

Dear Joseph, I have configured an ISP vlan (layer 2) on my Cisco 3750-1 and trunked to other Cisco 3750-2 where i have Layer 4 Firewall which does all the NAT stuff and it is working like charm. now i have trunked this ISP vlan to another Cisco 3750-3 switch which resides in another business unit nearby. I want only this business unit not to exceed the speed of 8 mbps download and upload. Hope this clears up of what i exactly want to achieve.

Dear All, I am working on a scenario to limit the switch port on Cisco 3750 to have bandwidth of 8 mb/s up and down, currently this port is configured as trunk and i want to restrict vlan 10 (IP - 192.168.10.0/24) for 8 mb/s up and down. Need help in this regard. Regards, Talha

Dear Seb Rupik,
If i change my firewall subnet mask to /16 from /21 do firewall will automatically NAT the incoming subnets within the range ?? and i'll have eight more subnets from 192.168.8.0/24 - 192.168.15.254/24 and add route back from firewall to 3750 will resolve the vlans scenario.

Dear All,
I am working on a scenario where i have application firewall in place at edge of the network (internet edge) for the purpose of application and content filtering, besides that i have Cisco 3750 switch which is right now configured with a single vlan (in same subnet with firewall). Now as this subnet is getting full i am planning to add departmental vlans to distribute users. Right now the default gateway is firewall (192.168.0.1/21) for this vlan but if i add more vlans and after enabling ip routing i'll have to change the gateway to there respective vlan id in my Cisco 3750 switch. So my question here is how would i still implement the application and content filtering in this scenario to restrict my users in new and existing vlans ??
Current Network Topology
Internet <---- App Firewall (192.168.0.1/21) <---- Cisco 3750 (192.168.5.50/21) <---- Users switches

Talha

Dear All,
I am working on a scenario where i am using /21 mask with class C address. Now as i am running out of ip addresses i am thinking to increase my block size to /20 or /19. Right now with /21 mask no subnets have been configured except default vlan. There is an application firewall at the edge of network and has multiple internet connections and is doing all the NAT stuff and is configured with another class C address of 192.168.10.1 acting as a gateway for whole block of /21. what i want to do now is to increase the block size to /19 or /20 and configure subnets on my core switch so that i can make departmental vlans. My question here is with departmental vlans configured i have to change the gateway of to specific vlan ip so in this case how my application firewall which is acting as a gateway right now will function as i want users to restrict and follow policy on firewall. should i add this gateway ip 192.168.10.1 in proxy setting so that users are restricted accordingly ?? or there is something else i have to do in order to make this network work ?
Regards,
Talha
