I have looked through the search results and have the following based on an existing script.
This refers to a file "portTest" which looks like this:
139.xxx.xxx.xxx 7001#139.xxx.xxx.xxx 7011#139.xxx.xxx.xxx 2001#
If I echo the variable $i earlier in the script than the telnet command it prints the whole value up to #, but when it sends the telnet request the port is not included.

AGR(4) BSD Kernel Interfaces Manual AGR(4)NAME
agr -- link aggregation pseudo network interface driver
SYNOPSIS
pseudo-device agr
DESCRIPTION
The agr driver provides link aggregation functionality (a.k.a. L2 trunking or bonding).
It supports the IEEE 802.3ad Link Aggregation Control Protocol (LACP) and the Marker Protocol.
The agr driver supports the following link specific flags for ifconfig(8):
link0 Use the round-robin distribution algorithm. Don't use it unless you're really sure, because it violates the frame ordering rule.
-link0 Use the default distribution algorithm, which is based on the hash of DA/SA, TCI, and, if available, some upper layer protocol infor-
mation like ip(4) DA/SA.
link1 Disable LACP. Prevents any LACP or Marker messaging which leaves the ports in the default static configuration. Set this prior to
adding ports.
EXAMPLES
Create an agr interface, agr0, and attach re0 and re1 to it. In other words, aggregate re0 and re1 so that they can be used as a single
interface, agr0. The physical interfaces which are attached to the agr interface must not have any IP addresses, neither IPv4 nor IPv6.
ifconfig re0 inet xxx.xxx.xxx.xxx delete
ifconfig re0 inet6 fe80::xxxx:xxxx:xxxx:xxxx delete
ifconfig re1 inet xxx.xxx.xxx.xxx delete
ifconfig re1 inet6 fe80::xxxx:xxxx:xxxx:xxxx delete
ifconfig agr0 create
ifconfig agr0 agrport re0
ifconfig agr0 agrport re1
Destroy an interface created in the above example.
ifconfig agr0 -agrport re0
ifconfig agr0 -agrport re1
ifconfig agr0 destroy

HISTORY
The agr driver first appeared in NetBSD 4.0.
AUTHORS
The agr driver was written by YAMAMOTO Takashi.
BUGS
There is no way to configure LACP administrative variables, including system and port priorities. The current implementation of the agr
driver always performs active-mode LACP and uses 0x8000 as system and port priorities.
The agr driver uses the MAC address of the first-added physical interface as the MAC address of the agr interface itself. Thus, removing the
physical interface and using it for another purpose can result in non-unique MAC addresses.
The current implementation of the agr driver doesn't prevent unsafe operations like some ioctls against underlying physical interfaces. Such
operations can result in unexpected behaviors, and are strongly discouraged.
There is no way to configure agr interfaces without attaching physical interfaces.
Physical interfaces being added to the agr interface shouldn't have any addresses except for link level address. Otherwise, the attempt will
fail with EBUSY. Note that it includes an automatically assigned IPv6 link-local address.
