Hi all..
I have PXE clients in one vlan and 2 netware servers in another vlan out of
which one is DHCP server and another oneis proxy dhcp server .
As long as I keep clients in same Vlan it works fine but as soon as I take
them to different Vlan there is a problem.
I have used Ip helper-address
Hi all..
I have PXE clients in one vlan and 2 netware servers in another vlan out of
which one is DHCP server and another one gives TFTP server IP to the PXE
client..
As long as I keep clients in same Vlan it works fine but as soon as I take
them to different Vlan there is a problem.
I have used
f vlans by priority. STP would
recognize one of the primary (high priority vlan) channels as disabled, and
immediately start allowing all vlans to traverse the other channel.
I think though, to answer the original posters' question, what he needs to
do, is either implement the configuration
The thing is to understand the principle behind VLAN load balancing and
etherchannel.In VLAN Load balance you load balance VLANs on trunks which are
not etherchanneled and in case you do etherchannel then you dont need to do
VLAN Load balance,
In vlan load balance you give either high port
The best way to do this , for instance, is to have CatA be thr root bridge
for vlan2,
and CatB the root bridge for vlan3.
When you do this, CatC will use CatA trunk/channel for vlan 2 and CatB
trunk/channel for vlan3.
Remember the STP decision sequence:
1. Lowest Root BID
2. Lowest Path Cost to
As always thank for you for your input and ideas Cisco people.
Situation: I have 3 Cat 6500's (Cat A,Cat B, Cat C) Cat A and B are the
main backbone and have a Gigabit Channel between then. Cat A and B's
MSFC's are routing and each MSFC has a priority routing for a vlan and
o was aksing this question.
So a quick test and
a. there is nothing wrong wqith having secondary addressing on a VLAN -
though why you would want to do this at the moment escapes me.
b. DHCP with/without an IP helpder address will respond with an address from
the scope relating to the primary IP ad
