how can i find out the ip address or mac address of my 3com 2824 switch if it is not labelled?

Question

I am trying to configure our office lan. There is no info on the switch itself, and I can't find anything on or in the box, but I know there must be a way by doing something like a netstat from a connected computer. I only have access to macs, so windows utilities and 3coms setup won't work. Surely there's a command line interface?

Answer 1

An unmanaged switch does not have nor does it need an IP of its own. It only is a massive connector for IP's that are active!
From 3COM

The 3Com® Baseline Switch 2824 is a highly affordable, high-performance unmanaged Gigabit switch.

From the 3Com manual
PLUG-AND-PLAY UNMANAGED OPERATION
3Com Baseline switches operate straight out of the box, with no configuration required. Auto MDI/MDIX ports identify and adapt to the Ethernet cable type, eliminating the most common cabling errors and simplifying installation. Autosensing ports detect and adjust to the speed of the connected device to optimize network performance.

end of 3Com information from datasheet!

Now if it was a managed switch it would need one but since it does not need any management it works below the IP level and simply does not need any IP assignment!

There is no setup to a non-managed switch, it is a PLUG AN PLAY device connection other MAC/IP addresses to each other it plays no routing mode nor management of those connections!

Answer 2

You won't find it simply because there is no such thing. A hub or a switch do not have a MAC address nor an IP address because you never talki to them, they just relay packets..

Answer 3

You should be able to console in or telnet in to the switch itself or if you want to use netstat...

Displays protocol statistics and current TCP/IP network connections.

NETSTAT [-a] [-b] [-e] [-n] [-o] [-p proto] [-r] [-s] [-v] [interval]

-a Displays all connections and listening ports.
-b Displays the executable involved in creating each connection or
listening port. In some cases well-known executables host
multiple independent components, and in these cases the
sequence of components involved in creating the connection
or listening port is displayed. In this case the executable
name is in [] at the bottom, on top is the component it called,
and so forth until TCP/IP was reached. Note that this option
can be time-consuming and will fail unless you have sufficient
permissions.
-e Displays Ethernet statistics. This may be combined with the -s
option.
-n Displays addresses and port numbers in numerical form.
-o Displays the owning process ID associated with each connection.
-p proto Shows connections for the protocol specified by proto; proto
may be any of: TCP, UDP, TCPv6, or UDPv6. If used with the -s
option to display per-protocol statistics, proto may be any of:
IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6.
-r Displays the routing table.
-s Displays per-protocol statistics. By default, statistics are
shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6;
the -p option may be used to specify a subset of the default.
-v When used in conjunction with -b, will display sequence of
components involved in creating the connection or listening
port for all executables.
interval Redisplays selected statistics, pausing interval seconds
between each display. Press CTRL+C to stop redisplaying
statistics. If omitted, netstat will print the current
configuration information once.

Answer 4

From command prompt type ipconfig /all and hit enter. It should specify the IP address in the output any more questions ask me.

Answer 5

if you let it set up to a router then in the lan resource status will tell you

Answer 6

Have you tried looking in your owners manual?
