Brocade DHCP on 7450 Switch

Leave a comment Posted by on July 5, 2017

I had the need today to setup DHCP on a Brocade 7450 Switch. I had never done this before, but very straight forward. Thought I would document how to/options if anyone ever needs it.

DHCP pool to create – TX-POOL, scope 192.168.6.0/24

config t

ip dhcp-server pool TX-POOL
dhcp-default-router 192.168.6.1
dns-server 192.168.1.183
excluded-address 192.168.6.1 192.168.6.10
lease 1 0 0
network 192.168.6.0 255.255.255.0
deploy

Notice the “Deploy” option – this puts everything into motion. Lots more options available like Domain-name, Options, lease times, etc.

To make sure everything is working you have some great show commands:

Brocade MGMT Vlan

Leave a comment Posted by on October 6, 2016

I recently installed quite a few Brocade 6450 switches. Great switches by the way, easy to use, very full CLI, great hardware. Most of Brocades (given its a L3 switch) switches support both routing code and switching code. I mostly deploy the Routing code, just my preference. But, in this scenario the 6450 was being deployed for a very small classroom, and no need to setup the routing interface, etc. so the instructions are for a switch running Switching code – you can check VIA show version command.

In this case we have a very specific vlan for management of networking gear, so I need the IP/GW to be on the vlan – in this case vlan 255. Below is how

Lets first create the vlan in CLI:

config t

vlan 255 name MGMT
 tagged ethe 1/2/1   (My uplink port)
 management-vlan
 ip address 10.44.255.100 255.255.255.0
 default-gateway  10.44.255.1 1

Lets run over a few things here.

  • First the vlan has to be tagged on a port, or untagged to actually show up in the config. Here I am tagging my uplink port 1/2/1
  • The management-vlan command has to be used on the Vlan you want for management, otherwise its the default vlan setup in the switch which by default is 1.
  • the default gateway commands needs the metric of the IP at the end. You can specify a value from 1 – 5. There is no default. The software uses the gateway with the lowest metric.

Configuring an IP address and enabling services such as SSH/HTTPS on Brocade Vyatta CLI

5 Comments Posted by on June 18, 2015

When Brocade purchased Vyatta I was nervous, but they have done a really good job with it. They keep it updated, and now have added a lot of functionality and increased services with the 6400 version. Both the 5600 (pretty much old vyatta) and the newer 6400 Vyatta IOS are for free from Brocade fro 60 days.

This blog entry is just showing some very simple things such as adding a IP address to an interface and enabling the HTTPS and SSH service. In another entry i will show how to use other user authentication methods for user logins. Although all of these commands are very easy, this post could help someone who might be in a bind.

Configure an IP address.

The Vrouter CLI has always been intuitive for me. Each config option is really an objects configuration. You can delete the config altogether or just an individual config setting of the object. To set the IP address first you have to go into configure mode.

configure

set int ethernet eth0 address 192.168.252.1/24

commit — remember nothing is set, until this is entered.

The image below shows these commands in the actual CLI.

ip-1

We can also save the config in config mode by issuing the command “save”.

That’s, it we have now set an IP address.So on to enabling SSH and HTTPS access.

HTTPS

To enable HTTPS we need to issue the command (from config mode)

set service https

commit

As you can see from the image below, after those commands are entered the Vyatta generates a certificate, and restarts its web server.

https2

SSH

Enabling SSH is as easy as the other commands.

From config mode

set service ssh enable

commit

You also have options to allow root login, set the listen address, and change the port.
