issue with show mac-address ?

[chukwuma]

when i run the show mac address-table it doesn't show the address option and | for the output modifier. why?

when i give the command it displays this below;

AZ-SWO1#show mac address-table

Mac Address Table

-------------------------------------------

Vlan Mac Address Type Ports

---- ----------- -------- -----

1 0040.0b72.5c01 DYNAMIC Gig1/0/2

1 0060.70b0.dc02 DYNAMIC Gig1/0/1

1 00d0.d39b.8a03 DYNAMIC Gig1/0/3

1 00d0.d39b.8a04 DYNAMIC Gig1/0/4

but when i issue this command below, it gives an invalid input;

AZ-SWO1#show mac address-table 0040.0b72.5c01

                               ^

% Invalid input detected at '^' marker.

then trying to check the options i have here is what i get

you can see both the address(to locate a specific mac address) and the pip(for modefier) is not there

AZ-SWO1#show mac address-table ?

     dynamic                   dynamic entry type

     interface                 List MAC adresses on a specific interface

     static                    static entry type

     <cr>

please what could be the reason for the invalid input ant the asbsence of the address and the pip?

HI,

What is the model of switch  and software version running on that switch?

Thanks

John

[chukwuma]

device model is 3650-24ps

The latest code do support that command :

#show mac address-table address  ( H.H.H 48 bit mac address)

what  model of the device, and IOS code running

another way to get only specific 

#show mac address-table | in 0040.0b72.5c01

[chukwuma]

the invalid input marker sign ^ also appears under the | (pip) as well as under the address.

Or could it be because i am learning with packet tracer

Hello,

I have a hunch that you are doing this in Packet Tracer ? PT is not a 'real' switch, but rather a simulator with just a limited amount of commands available compared to what you what see in a full IOS switch.

In Packet Tracer, you get this (identical to your output):

Switch#sh mac address-table ?
dynamic dynamic entry type
interfaces interface entry type
static static entry type

A full IOS switch would give you something like this:

Switch#sh mac address-table ?
address Address to lookup in the table
aging-time MAC address table aging parameters
count Number of MAC addresses in the table
dynamic List dynamic MAC addresses
interface List MAC adresses on a specific interface
multicast List multicast MAC addresses
secure List secure MAC addresses
static List static MAC addresses
vlan List MAC addresses on a specific vlan
| Output modifiers

[chukwuma]

yes 

you are very correct

But is there no way out?

Or should i just continue?

[Georg Pauwen]

Hello,

with Packet Tracer, you have no other options than those you see. What specific task are you working on ?

[chukwuma]

okay.

i am taking some tutorials from CBT nuggets. So, as part of excersices, i'm working on how to locate devices on a switch network.

if you can give me any further guidiance i will appreciate

thanks
