I have connected an ASA 5520 firewall DMZ to SERVER (55) vlan in core switch and INSIDE is connected as trunk to the core switch (including vlan 66,77). now the management ip of the switch is 10.xx.xx.126/25. and the other vlans are showing "administratively down"..but if I enter to any of the other vlans and do a "no shut", that particular vlan wil go UP but the other 2 will go down..means only one vlan become up at a time....what could be the cause??? Please help….
