I'm quite new to Extreme and have yet some limited knowledge about XOS.
But the story is that i have replaced our core router (X440-24t) with two "new" X440-24t in stack.
Firmware version 18.104.22.168 as Extreme recommends for the X440.
I have copied most of the configuration from the old one.
Management port connected with cable to switch port 1:1 with untagged VLAN401
I did run the stack config-guide-thingie and it went wonderful, and at the lab where i set them up it worked perfectly.
I have it set them to act as router for 3 ip ranges.
But when i moved the switches to the server room i began to get random access to the mgmt interface. Tho all traffic to and from configured VLANs are working perfect.
After a lot of troubleshooting i noticed that i can access the mgmt-cli via our external IP's that i have configured in the switch, now, i thought this was not possible after reading a lot on vr-mgmt access.
I have also random access for outgoing traffic from vr-mgmt to any, basically, for ex. ping google it works sometime but most of the time it does not.
But when i access SSH thru our external IP i get no errors or disconnect from cli as i get when connected thru the internal IP i have setup on the mgmt vlan.
I can access the mgmt-cli thru any of the VLAN105X ip addresses.
Now, what have i done wrong?
configure vlan default delete ports all
configure vr VR-Default delete ports 1:1-24,2:1-24
configure vr VR-Default add ports 1:1-24,2:1-24
configure vlan default delete ports 1:1-24,2:1-24
enable jumbo-frame ports all
configure vman ethertype 0x8100 secondary[/code]configure iproute add default 172.16.254.1 vr VR-Mgmt
configure iproute add default xx.xxx.88.93

I also noticed that when im doing an arping from an linux machine i get this
# arping -D -I ens32 -c 6 172.16.254.254
ARPING 172.16.254.254 from 0.0.0.0 ens32

# sh iparp vr "VR-Mgmt"
