Hello,   I have an ASA firewall pair configured as active/standby but the previous administrator did not configure the failover state. The current active firewall is the secondary. What do I need to configure in order for a successful implementation of the state? Do I only configure state link and IP address on the secondary - active or do i need to do something else?   Regards,   Nicos ... View more

Hello community, I had a spanning-tree issue a while ago with 3 switches and I am cracking my head of why this happened. I need an explenation for future reference. I had a 3750 acting as a L3 switch and a 2960 trunked behind the 3750. All switches had IP phones plugged in. I have put an old 2900 or 3550 switch behind the 2960, in trunk and configured to allow only the Voice VLAN. No redundant uplinks. When i put the old switch, phones in the 2960 (middle) were disconnected and were in 'Registering' phase. The old switch was the STP root for the voice VLAN. I have changed STP priority and everything worked fine. My question is: why did this happen? STP is a loop prevending mechanism. I had no loops. But I caused partial downtime. And even if the old switch was the root bridge, it would still try and send traffic to the default gateway, right? Can anyone explain please? TIA, Nicos Nicolaides        ... View more

Hello, We have WiSM for WLAN deployed in our premises and we are going to open a new branch. I was thinking to install a Cisco 897VA router in the new branch but I would like centralised wireless management managed by the WiSM controller. My question is if WiSM supports the AP on the Cisco 897VA router and if it is going to be supported in the 5508 and 2504 controllers as well. TIA, Nicos Nicolaides        ... View more
