13 Feb 17 Brocade ICX 6450-24P PoE and PoE+

Brocade ICX 6450-24P PoE and PoE+ Limitations and Configuration

Recently ran into a minor issue when I was connecting Cisco Meraki MR72’s to a Brocade ICX 6450-24P. Connected 13 Cisco Meraki MR72’s. I was consoled into the switch so I noticed all ports showed getting power but the PoE was denied on port ethernet1/1/24. Looking at the command show inline power I noticed that all Cisco Meraki MR72’s were showing up as Class 4 and ports were doing by default 802.3at/30,000mWatts which means my 13th Access Point was not getting any power because ethernet1/1/24 had only 10,000mWatts left.

In order to resolve this so that I can get the last Cisco Meraki MR72 online. I first confirmed the power these Access Points require. And according to the documentation for Cisco Meraki MR72’s they do support 802.3af. My next step was to update the ports on the Brocade ICX 6450-24P as follows:

interface ethernet 1/1/24
dual-mode 1
disable
spanning-tree root-protect
spanning-tree 802-1w admin-edge-port
inline power power-limit 15400 (THIS COMMAND BASICALLY FORCED THE PORT TO LIMIT THE POWER)
stp-bpdu-guard

After I ran the above command inline power power-limit 15400 under couple of ports I had enough power available and was able to successfully bring up all 13 Access Points online. Here is a document that shows ICX 6430 – 6450 Data Sheet. Also check out the picture below, basically on a 24 port switch if you want all 24 ports to be able to operate at PoE+ you will need additional power supply.

11 Nov 16 Brocade ICX 6450 PoE Configuration

Enabling Power over Ethernet on Brocade ICX6450

Recently I configured a Brocade ICX6450 PoE switch on the network and all was working well until my customer hooked up a phone to one of the ports I configured. I was told that the phone won’t power on. Now on a Cisco PoE Switch, I’m used to just simply plugging in phones and getting power. With the Brocade ICX6450 I needed to perform some additional steps to get it working.

First I ran the following command to check the PoE Status on the port in question:


show inline power 3/1/17
This gave me the following results:
Port Admin Oper ---Power(mWatts)--- PD Type PD Class Pri Fault/
State State Consumed Allocated Error
--------------------------------------------------------------------------
3/1/17 Off Off 0 0 n/a n/a 3 n/a

As you can see under the “Admin State/Oper State” both are showing “Off”. Which means there is no Power over Ethernet is enabled on these ports. So in order to enable it I needed to do the following:


conf t
!
interface ethernet 3/1/17 to 3/1/24
inline power (***note: no inline power will disable it)
-------------------------------------------------------------------
Now lets look at it again
Port Admin Oper ---Power(mWatts)--- PD Type PD Class Pri Fault/
State State Consumed Allocated Error
--------------------------------------------------------------------------
3/1/17 On Off 0 0 n/a n/a 3 n/a


Port Admin Oper ---Power(mWatts)--- PD Type PD Class Pri Fault/
State State Consumed Allocated Error
--------------------------------------------------------------------------
3/1/1 Off Off 0 0 n/a n/a 3 n/a
3/1/2 Off Off 0 0 n/a n/a 3 n/a
3/1/3 Off Off 0 0 n/a n/a 3 n/a
3/1/4 Off Off 0 0 n/a n/a 3 n/a
3/1/5 Off Off 0 0 n/a n/a 3 n/a
3/1/6 Off Off 0 0 n/a n/a 3 n/a
3/1/7 Off Off 0 0 n/a n/a 3 n/a
3/1/8 Off Off 0 0 n/a n/a 3 n/a
3/1/9 Off Off 0 0 n/a n/a 3 n/a
3/1/10 Off Off 0 0 n/a n/a 3 n/a
3/1/11 Off Off 0 0 n/a n/a 3 n/a
3/1/12 Off Off 0 0 n/a n/a 3 n/a
3/1/13 Off Off 0 0 n/a n/a 3 n/a
3/1/14 Off Off 0 0 n/a n/a 3 n/a
3/1/15 Off Off 0 0 n/a n/a 3 n/a
3/1/16 Off Off 0 0 n/a n/a 3 n/a
3/1/17 On Off 0 0 n/a n/a 3 n/a
3/1/18 On Off 0 0 n/a n/a 3 n/a
3/1/19 On Off 0 0 n/a n/a 3 n/a
3/1/20 On Off 0 0 n/a n/a 3 n/a
3/1/21 On Off 0 0 n/a n/a 3 n/a
3/1/22 On Off 0 0 n/a n/a 3 n/a
3/1/23 On Off 0 0 n/a n/a 3 n/a
3/1/24 On On 2441 4955 802.3af Class 2 3 n/a

Now you can see that the “Admin State” of Power over Ethernet is showing “On”. When my customer plugged in the phone, it came online successfully. I do not know why Brocade ICX6450 has it like this, seems very unproductive but oh well its Brocade.

I’d like to also add a link to Brocades Switch Administration Guide that has some additional details if someone is interested. FastIron Ethernet Switch Administration Guide Supporting FastIron Software Release 08.0.30

07 Oct 16 Brocade 6450 switching to Routing Code

Brocade 6450 switching to routing Code

So recently I had to work on a Brocade 6450 Switch. I needed to create SVI’s on the switch but I was not able to do that with a switch right out of the box. Reason is because by default it uses the “switching code”, when you do “show ver” you will see “S” in the code. But you can do “show flash” and you will see a secondary flash code with “R” in there. That is the code that allows you to make it a L3 switch. Here is what I did to make it a L3 switch:

conf t
!
boot system flash secondary
wr mem
##### Verify ######
show boot (Make sure secondary is default)
###################
reload

Once the switch comes back up now you it was in L3 mode and I was able to create SVI’s. This was done on a switch with no configuration on it. If someone decides to do it on a production switch make sure you back up your configuration and keep in mind that this process will cause down time.
