How to enable “mgmt0” aka management interface of Cisco Sup2T

Last day,

during the two 6509e Supervisor migration, we had to upgrade the IOS, humbling around to enable and assign a static ip address to the management interface located in the front pannel of the sup2T .

sup2t

This link to Cisco explain very well the functionality of this special port, in fact it’s very different as “we” intend a mgmt interface.

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/cmp_configuration/guide/sup2T_10GEcmp.html

Table 1-3 Explain very well the combination sequence to enable it.

Table 1-3 Switching Access Between RP and CMP on a Console Connection

Action

Control Sequence
RP to CMP Press Ctrl-c and then Shiftm 3 times consecutively:
Ctrl-c Shift-m Ctrl-c Shift-m Ctrl-c Shift-m
CMP to RP Press Ctrl r and then Shift m 3 times consecutively:
Ctrl-r Shift-m Ctrl-r Shift-m Ctrl-r Shift-m 

Once enable, we are going to configure it for transfering the new IOS image.

1. configure terminal

2. interface cmpmgmt

3. ip default gateway ipv4-address

4. ip address ipv4-address/length

5. end

6. show running-config

Now it’s time to start the tftp or ftp server and start to transfer the new IOS

Copying Files from the CMP to RP Disk0: or Bootdisk:

To copy files from a TFTP server on teh CMP to a compact flash disk in disk0: or bootdisk: on the RP, perform this task:

 

Command

Purpose
switch-cmp# copy tftp: [rp-bootdisk:rp-bootdisk:] Transfers files from a TFTP server on the CMP to a compact flash disk in disk0: or bootdisk: on the RP.

Network speed test with FreeNas

Here some  transfering rate about 400Gb in once, but remember it’s only a raid 1 with 2 disk 3Tb 7200rpm WD Green, not the best one for a NAS Build.

and the transfert was from a laptop with attached a hdd on usb to Freenas, so not so bad.

In fact it’s about 30Mb/s against 15Mb with Qnap.

here some screen:

What about ram? Yes I know, 4Gb for FreeNAS is not enough if you want use ZFS, I’m planning to add a 4Gb stick more, and one hdd maybe SSD for caching.

Memory

What about networking? Yes I’ve bundled the 2 port via LACP on Cisco, but this way you loose connection with the IPMI Management that is share across the ETH-01, I’m looking to get rid of it.

Now it’s time for a little trick: working last 2 week for the ESXi-lab with only a Jbod for testing purpose, now I need to copy my Datastore from a disk to the new 2Tb Raid-1, so I’m not so familiar with freeBSD, and googling around I’ve found this nice little trick, and I want to share:

From the FreeNAS shell or via ssh type:

  • rsync -av –log-file=/mnt/source/rsync.log /mnt/source /mnt/destination
Where :  --log-file  log detailed the end of operations
         /mnt/source is the mount point ZFS source disk
         /mnt/destination is the mount point ZFS destination disk

You have to wait a bit, depends on how many GB it has to clone.
Remember to look at the log at the end of operation.

VMware ESXi White Box – building the lab part1

Hi all,

enticed and inspired for about 1 year by Chris Wahl  [ http://wahlnetwork.com] for his home-lab, here it is:

Actually there’s not failover due to hw cost, system is build:

  • 1. CPU: Intel Xeon E3-1230 “Sandy Bridge” – 3.2GHz, 4 Cores, 8 Threads, 8MB
  • 2. Motherboard: Supermicro X9SCM-F – Intel C204, Dual GigE, IPMI w/Virtual Media, 2x SATA-3, 4x SATA-2
  • 3. RAM: 16GB (4 x 4GB) Kingston 240-Pin DDR3 SDRAM ECC Unbuffered DDR3 1333 (PC3 10600) Server Memory Model
  • 4. USB-Stick: 16GB Supersonic Xpress USB 3.0 Flash Drive (PSF16GXPUSB)
  • 5. Power: Seasonic 400W 80 Plus Gold Fanless ATX12V/EPS12V Power Supply

I’m actually testing some NFS with my other NAS-build with FreeNAS some picture below:
