# WHATPORT(2702)

## NAME

port 2702 — SMS/SCCM Remote Control transfer — The companion data channel to 2701, registered by Microsoft as SMS XFER.

Protocol: TCP  
IANA: sms-xfer

## DESCRIPTION

IANA holds 2702 for Microsoft as "SMS XFER", the transfer side of SMS/SCCM remote tools that sits next to the control channel on 2701. Firewall guidance for remote control has long paired the two, though the current Configuration Manager port table lists only 2701 for remote control. In practice you see 2702 alongside 2701 on ConfigMgr-managed Windows clients and essentially nowhere else.

## EXPOSURE

**Do not expose.** It only means anything next to 2701, and it inherits the same rule — remote control of managed desktops stays on the internal management network.

## CHECK

```sh
nc -vz -w 3 TARGET 2702
```
