And changing | awk print in=$4 }.
By doing that would I be able to call “in” and get the output?
I still have no idea what you mean by 'call in'.
This command is extremely inefficient. Can you show complete output from ./check_snmp_int.pl -H 192.168.1.1 -C public -n eth0 -k --label -w 0,0 -c 0,0 -d 15 -MB and highlight the parts you want, please? You can probably do it all in one awk.
You can open commands like
...but it would be far better to simplify the command you have than use it blindly. You may not need C at all.

arpsend - send ARP requests
SYNOPSIS
arpsend -D -e target_ip [ -e target_ip ...] [-c count] [-w timeout] interface
arpsend -U -i source_ip [-c count] [-w timeout] interface
DESCRIPTION
Utility arpsend sends ARP packets on device interface to detect or update neighbours' ARP caches with a given IP.
COMMANDS
Run utility with one of the following commands:
-D Send broadcast ARP request to detect neighbours with target_ip. You have to specify target_ip (-e option).
-U Send broadcast ARP request to update neighbours' ARP caches with source_ip. You have to specify source_ip (-i option).
OPTIONS -c count
Number of packets to send. Default is infinity.
-w interval
Interval between packets, in seconds. Default is 1 second.
-i source_ip_address
Set source IP address field in ARP packet.
-e target_ip_address
Set target IP address field in ARP packet. Note that you can specify -e option multiple times to detect many IP addresses in one
utility call.
EXIT STATUS
arpsend returns 0 upon successful execution. If something goes wrong, it returns an appropriate error code.
1 EXC_USAGE
Usage error
2 EXC_SYSTEM
System error
3 EXC_RECV
ARP reply was received
EXAMPLES
To send request on interface eth0 to detect any neighbour computers with IP 192.168.10.200:
arpsend -D -e 192.168.10.200 eth0
To send request on interface eth0 to update neighbours' ARP caches with IP 192.168.10.200:
arpsend -U -i 192.168.10.200 eth0
NOTES
Interface you use have to be arpable and not be loopback (i.e. /sbin/ip link show interface should show neither NOARP nor LOOPBACK flags
in interface parameters).
