# WHATPORT(3071)

## NAME

port 3071 — xplat-replicate (NetApp) — Reassigned in 2017 to NetApp's crossplatform replication protocol; older /etc/services files still call it ContinuStor.

Protocol: TCP  
IANA registry

## DESCRIPTION

The current IANA registration for TCP 3071 is `xplat-replicate`, "Crossplatform replication protocol", held by NetApp since 2017-08-24; the UDP side is marked Reserved. Many systems still ship an older services file naming 3071 `csd-mgmt-port`, ContinuStor Manager Port, so scanner output and the registry disagree. There is no public protocol document for either name. In practice you see 3071 only around NetApp storage software, and otherwise not at all.

## EXPOSURE

**Expose with care.** If it really is storage replication it belongs on a private replication network; if it is something else entirely, fingerprint it before you decide.

## CHECK

```sh
nc -vz TARGET 3071
```
