Is there an easy way to stack Cisco 2960-S and Cisco 2960X switches? If you have no idea, follow this:
1. Stacking is not supported on switches running the LAN Lite image. All switches in the stack must be running the LAN Base image.
2. In a mixed stack of Catalyst 2960-X and Catalyst 2960-S switches, the number of supported stack members is reduced from eight to four.
3. In a mixed stack of Catalyst 2960-X and Catalyst 2960-S switches, full stack bandwidth is reduced from 80 Gbps to 40 Gbps.
4. In a mixed stack of Catalyst 2960-X and Catalyst 2960-S switches, stack convergence time is increased from milliseconds to 1 to 2 seconds.
Hey,
Im a high school student in Cisco, Im in CCNA 3 right now and we are starting our Linux stuff, but our instructor can't seem find a good FREE RedHat 9 ISO, could anyone help out with this and send us some links. :)
Thanx a lot. (4 Replies)

SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $ciscostats = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
# These arguments are passed directly on to SNMP::Session
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.
";
my $class = $ciscostats->class();
print "SNMP::Info determined this device to fall under subclass : $class
";
DESCRIPTION
SNMP::Info::CiscoStats is a subclass of SNMP::Info that provides cpu, memory, os and version information about Cisco Devices.
