Hi Sammi,
You can create
10.200.1.x/24 as VLAN 1
10.200.2.x/24 as VLAN 2
this will isolate the broadcast within the VLAN.
You can't create
10.200.1.x/16 as VLAN 1
10.200.2.x/16 or /24 as VLAN 2
because VLAN 2 will become part of VLAN 1, does not serve the purpose of
having VLAN configuration

Yes, seem like that's the current solutions. But this will create high
overhead on routers, imagine every 3 secs of Hello packets means every 3
secs of encryption and decrytion and what if there are multiple groups?

Hi,
What could cause a HSRP state change if the router is not down? It's very
difficult to debug since there is no pre-determine time of when this will
happen? There is nothing to do with the recent HSRP DoS for sure :), since I
have implemented the necessary steps to overcome it.

ow which segment the station is on,
look at the local router's arp table to determine the MAC address
3) Look at the switch(s) to find the port the MAC is on and then
trace to the physical station and investigate

Hi,
Anyone knows how to enable ACL or some form of telnet control to the switch.
Is there any instructions on how to control the SNMP query as well.
Thanks,
