How can I match conditions when I show arp?
In my Cisco Router I check the arp:
Router>show arp
Protocol Address Age (min) Hardware Addr Type Interface
Internet 192.168.1.1 - 0001.42D2.AE01 ARPA GigabitEthernet0/0/0
Internet 192.168.1.2 67 000C.CF4C.99E6 ARPA GigabitEthernet0/0/0
Internet 192.168.2.1 - 0001.42D2.AE02 ARPA GigabitEthernet0/0/1
Internet 192.168.2.2 109 0010.114E.A4EC ARPA GigabitEthernet0/0/1
I want to match conditions, but I tried bellow, all do not work:
Router>show arp | match 192.168.2.2
^
% Invalid input detected at '^' marker.
Router>show arp 192.168.2.2
^
% Invalid input detected at '^' marker.
I also tried the begin, or include:
Router#show arp | begin ?
% Unrecognized command
UPDATE
The show version display this:
Cisco IOS XE Software, Version 03.16.05.S - Extended Support Release
Cisco IOS Software, ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version Version 15.5 (3)S5, RELEASE SOFTWARE (fc2)
this is a ISR 4321 Router.

For most varieties of Cisco IOS. (For the ISR 4321 it appears the answer is different, see later.)
To start with matching, use | begin:
gw>show arp | begin 192.168.0.32
Internet 192.168.0.32 0 90fb.a630.1234 ARPA Vlan1
Internet 192.168.0.36 0 0004.2012.4321 ARPA Vlan1
...
There are a few varieties:
gw>show arp | ?
begin Begin with the line that matches
count Count number of lines which match regexp
exclude Exclude lines that match
format Format the output using the specified spec file
include Include lines that match
section Filter a section of output
But there's something funny going on if you can't do the basic:
gw>show arp 192.168.0.32
Protocol Address Age (min) Hardware Addr Type Interface
Internet 192.168.0.32 0 90fb.a630.1234 ARPA Vlan1
What model and version are you using?
ISR-4321
Per Cown's comment:
Ok i found the error i think, you need to use show ip arp | in 192.168.2.2
Packet tracer
As suggested by Cown in comments, if you're using Packet Tracer, not a real router, you have to be in enable mode.
