In the past you have helped me, so we will try again once more...
I have two of these switches, connected via a fiber gigabit interface. Switches are called Command, and Member1. Both vlan1 have ips.
Question 1: How do I know if there has been a release to the IOS, and what advantages are there to upgrading. Is it mostly security updates, or feature updates when a new IOS is released.
Question 2: I've setup MRTG, to monitor the bandwith being used on the ports, and I noticed there is simply a tone of SNMP OIDs, currently everything is enabled in a group called "Everything" as read only. Is this a security issue? Should I only let certain OIDs be available, if so where can I read more about what they actually are...
Question 3: When I try to save my configuration to my TFTP server, I get the following error message. "%Error opening flash:vlan.dat (No such file or directory)". Upon inspection, I noticed that the file vlan.dat is missing from Command, but is present on Member1. I know I didn't delete it, so how do I regenerate the file, or what should I do?
Question 4: Last question.. I need to be able to find out what IP address is assigned to a port on a switch. I tried using the mac-address-table, but it's not showing all the ports. I know it's because there hasn't been any activity and it's removed the data, but is there not a way for me to query a specific port, and find out it's the mac address of the ethernet card attached.. Then ping .255 and do an arp -a to find it's ip? Maybe I have to enable something on the switch..
I know this is a lot of questions... hope someone can point me in the right direction.
