Hi felart18,   What OS version are you running? Also try using no spaces when defining the range. Page 789 [URL] In addition if the VLANs were not created locally the range command doesn’t work.
Hi,   I'm trying to configure a range configuration from VLAN 500 to VLAN 1000 on a S4810 but is erroring out:   s4810p-stack(conf)#interface range vlan 500 - 1000^% Error: In configuration at "^" marker.s4810p-stack(conf)#   If I do it on a normal port, it works fine: s4810p-stack(conf)#interface range te0/0-5s4810p-stack(conf-if-range-te-0/0-5)#   I can configure the VLAN interface one by one, but that will take too long. What am I missing here? Thanks,
