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.
