VMware’s Online Depot for VMware Image Builder

I am posting this because for some odd reason it seems nearly impossible to find this in any of Vmware’s documentation on ImageBuilder.  It mentions you can add online repo’s but never gives a link to their online repo with all the ESXi builds.

I recently ran across some links and blogs that listed that path.  So, in order to get the online depot imported use this:

Add-EsxSoftwareDepot https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml

esxcli software vib install -d Update-Depot

VMware PowerCLI update

$esxcli = Get-EsxCli -VMhost 192.168.123.123

$esxcli.software.sources.profile.list("/vmfs/volumes/PRG0100-NETAPP02B-ISOARCHIVE01/ISO/VMware/5.5/ESXi550-201505002-build2718055.zip")

#$esxcli.software.profile.update($null, "/vmfs/volumes/PRG0100-NETAPP02B-ISOARCHIVE01/ISO/VMware/5.5/ESXi550-201505002-build2718055.zip", $null, $null, $null, $null, $null, "ESXi-5.5.0-20150504001-standard", $null)

Force10 ECMP & static Routes

Hi,

Just to clarify for group (as I got few email on this)

When a static route is configured it will be loaded in the routing table if the next interface (physical or vlan) is up but they won’t be any arp check on the next-hop (unless you set the PBR rules for that)

So a use case would be :

SW1 : static route to reach Lo(Sw2) / next hop = SW2 IP (in int vlan 2)

SW2 : static route to reach Lo(Sw1) / next hop = SW1 IP (in int vlan 2)

Lo(Sw1) ----- Sw1_Ten 0/1 --- (vlan inter 2)--- Sw2_Ten 0/2 ----- Lo(Sw2)

if the vlan 2 has other ports that are up, even though the link that interconnects sw1 and sw2 goes (physically) down,  the packet to the loopback get black hole (no route re-calculation since the static route is still in the routing table)

Hi,

We’re not checking next hop availability (thought arp) for static routes you need to use PBR rules for that.

All of this being not related to ECMP.

Dell - Internal Use - Confidential

Hi All,

I´m doing test with ECMP and static routes in order to provide route redundancy.

I configured the following:

ip ecmp weighted

ip route 12.1.1.9/32 10.197.107.235 weight 10

ip route 12.1.1.9/32 10.197.107.234 weight 20

It is not working when the first gateways goes down

It is something wrong on my configuration?

Any comment will be very appreciated

Regards.

After it's done, check the value of the FRU Board Product Name typing "writefru" again and selecting option 1 "Read FRU Contents"
Reboot the board, when FTOS prompt comes back do a "show system brief".
You should see "ReqTyp" and "CurTyp" as "MXL-10/40GbE".
