Hello, colleagues. I've a task of sending WakeOnLan magic packets from one server through routed network to remote subnets.Curent configuration uses ip helper-address statment for every target network on router interface, where WOL server is located....
Hello, colleagues.We have faced an STP bug\problem, that later caused a switch-stack to brake.I would like to know, if anybody had faced similar problem before, and what could be the reason of it.Hardware is 2*WS-C3750G-48TS stacked with 15.0(2)SE11 ...
Hi, colleagues. I have a task of changing managment Vlan for all devices in the network.It's rather simple with L3 devices, but some kind of puzzle with access switches, which are 2960 in my company.Catch is: i have to maitain the IPs, but move it to...

Hello everybody, pending for advise.

CPU on ASR is not an issue in that case, we have more thsn 100 helper-addresses on another model, so I guess it depends on exact model or exact IOS feauture-set. Unfortunatley, I could not find in documentation, what exactly limits these statments.So...
That's an interesting thought!I do not realy want to go that way, it creates some unclear-hard-to-understand config.I still have an option to create multiple WOL-servers.But solution itself is cool, maybe I'll have to use it another time
For WOL purpose.Use-case and configuration example can be examined here:https://www.cisco.com/c/en/us/support/docs/switches/catalyst-3750-series-switches/91672-catl3-wol-vlans.html
when the devices could not ping did you check the arp table too , was it complete for these macs \\\yes, mac were seen correctly, including macs from another switch via trunkave you tried to replicate the issue \\\I dont see the way to replicate the ...
Thanks for sharing the scrypt.I'll try to modify it for my needs and use later, though it's a bit hard to be right now for me.Pitty, I can't give two "solutions" in one topic, so just thanks again!
