There is a small risk if the access lists allow the local networks on each device to talk to the management network.<br />
<br />
Normally you will want to stop the LAN interface from talking to the management interface to prevent someone jumping through the management switch to attack another location if they happen to breach the first location.

Hi,<br />
I was just wondering if there is any risk to have a management networks to connect different equipment from different networks. <br />
<br />
Let me explain<br />
If a have 3 different &nbsp;networks connected to 3 different routers( or switches).<br />
-A 192.168.1.0 Management: 10.10.10.1 port 15<br />
-B &nbsp;10.20.15.1 &nbsp;Management :10.10.10.2 port 15<br />
-C 192.168.4.0 Management: 10.10.10.3 Port 15<br />
<br />
If I connect the 3 port management on the same switch, to be able to manage all my networks from the same place, is there any risk to mix my A,B ,C networks?<br />
<br />
Thx.<br />
<br />

Manage all my networks from the same place

Network Operations includes asset management, help-desk supervision, security and user policies, infrastructure administration and anything else that affects the operation of your network. Discussions will include those of best practices in platforms, configurations, performance, security and accounting.

Network Operations

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
