Hardware type CN gigabit Ethernet

[Bob Greer]

Thanks for reading!

How is that different from "Hardware type is Gigabit Ethernet"

Servus!

Hi Bob,

Could you please provide more details about your questions?

Thanks

Hi Julio,

Thanks for replying.

I have a few routers with this output that I'd never before noticed:

rtmx301#show int g0/2
GigabitEthernet0/2 is administratively down, line protocol is down
  Hardware is CN Gigabit Ethernet, address is 
  MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,
     reliability 255/255, txload 1/255, rxload 1/255

I'm wondering what the CN specification means.

I remember is the type of hardware, but please let share an example.

[Bob Greer]

Is this what you mean?

NAME: "CISCO2921/K9", DESCR: "CISCO2921/K9 chassis, Hw Serial#: Hw Revision: 1.0"
PID: CISCO2921/K9      , VID: V08 , SN:

Here's the interesting part of the show int:

GigabitEthernet0/2 is administratively down, line protocol is down
  Hardware is CN Gigabit Ethernet, address is 
  MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation ARPA, loopback not set
  Keepalive set (10 sec)
  Auto Duplex, Auto Speed, media type is RJ45
  output flow-control is unsupported, input flow-control is unsupported
  ARP type: ARPA, ARP Timeout 04:00:00

I'm not sure what else to bring forward.

Usually it is associated to the chipset name. Sometimes CN is associated to Computer Number, are you seeing it on packet tracer?

For example:

Hardware is BCM1250

I'm seeing it on a physical CISCO2921/K9, not PacketTracer
