Hello, If you have already configured the default gateway on the interface there is no need in re-entering the configuration you will just need to enter the ip helper-address- the ip address where you want the broadcasts to be forwarded i.e DHCP Server. The command will bring up the entire configuration entered and running on the Cisco IOS including IP Helper. A more specific command to use would be . No the running configuration is local only if it is not showing it means it has not been configured on that switch. HTH  

thanks

Hello Guys, Just to clarify thin client is different to a VDI. ???? Virtualisation is VMware view and ESX, Hyper-V, Citrix xen Desktop Terminal services is ???????????????? Thanks

Shame it doesn't give the IP Address. Ill have a copy email it to hotmail. what's with the pic Thanks chris

Hello. in the access layer if you had a 48/24/whatever port switch would you use all the ports on that switch? Also which one do you prefer and why. 24 port or 48 port switches?

Hello I know this may be a bit of a daft question..... As part of my college project we have to design a network for a college and the network in question is to include 1 workstation in each 'normal' teaching room. I was wondering how many Ethernet drops real classrooms have and how many you would include for expansion e.t.c Thanks for any comments....

I prefer CBT Nuggets CBT Nuggets Home

I use sipgate TBH I don't use it much I set an account up with number and that's about it. > Skype > Some ISP's do home VOIP (I think BT have a package)

Interesting.... the cable seems very likely. Are these on VLAN's or something maybe someone has changed the switch configuration............. Have you checked the DHCP server see what's happening.

It really does depend on your organisation and there is no right or wrong way of what to use VLAN's for but work out what you want the VLAN's to achieve. Definetly one for VOIP though. There are two types of VLAN implementation: Local VLAN's- Local to that switching closet. End-to-end VLAN's- organisation wide. Cisco now recommend using Local VLAN's there are advantages and disadvantage to both along with best practices. One reason for the change is Layer 3 distribution. I tend to go for the functionality route. How about: VLAN for IT roos VLAN for Library VLAN for administration and staff room VLAN for sixth form VLAN for humanities VLAN for ..... Anyway hope it helps.

VLAN sounds good. Don't forget the ACL's to block the VLAN from being routed to the rest of the network/VLAN's :-) I haven't read the other thread but they probably set the RADIUS up for authentication.

As long as the router/UTM provides the required throughput and interface card you will be fine. A Cisco 2600XM should be ok with a 100MB connection, that said if your running the firewall/IPS/VPN combined with a high amount of users....!!!!

VLAN's are not the answer to every problem BUT they are better than no security. I have no experience is HP but from a Cisco view: There are various ways to mitigate VLAN hopping. As quoted by Cisco: Network Attack Mitigation Mitigating VLAN hopping attacks requires several modifications to the VLAN configuration. One of the more important elements is to use dedicated VLAN IDs for all trunk ports. Also, disable all unused switch ports and place them in an unused VLAN. Set all user ports to nontrunking mode by explicitly turning off DTP on those ports (source:http://www.cisco.com/warp/public/cc/so/cuso/epso/sqfr/sfblu_wp.pdf) In= In to the device Out= Out the device The general rule is to put Extended ACL's closest to the source and standard ACL's closest to the destination. Anyway hope it helps.
