VMware: How to Enable CDP On ESX3.X Host

August 6th, 2009 5 comments

VMWare has made CDP (Cisco Discovery Protocol ) available to their host.

When you the CDP is running on router/switch where the physical network card is connected it provide information to both Network administrator and ESX admin about host name/network card. This information help when you are trying to figure out which network card on the host is connected to which physical switch

 

B|–set-cdp          Set the CDP status for a given virtual switch.
                        To set pass one of “down”, “listen”, “advertise”, “both”

On this ESX host we got 3 vSwitches, you need to enable the CDP feature for each vSwitch like (putty or console):

[root@ESX-vm2 root]# esxcfg-vswitch -B both vSwitch0
[root@ESX-vm2 root]# esxcfg-vswitch -B both vSwitch1
[root@ESX-vm2 root]# esxcfg-vswitch -B both vSwitch2

 

Now in vCenter 2.5 you see the Configuration > Networking > vSwitches, in te little comment box you can click:

Cisco:Bandwidth Monitoring Tool: Fireplotter

March 5th, 2009 No comments

Wij constateren performance issues op de WAN interface maar de oorzaak is niet duidelijk. Men klaagt over traag internet maar toch blijft het moeilijk om het e.e.a. uit te lezen waar en wie nou die bandbreedte weg trekt.

De applicatie Fireplotter kan d.m.v. SSH of Telnet een connectie opzetten naar je Cisco PIX/ASA

Here you can select Cisco ASA/PIX or FortiNet FortiGate firewall type

Na enige periode te hebben gelogged krijg je een beeld met wie / wat performance wegneemt van je bandbreedte.

As an aside, notice, that if you click on the word Sessions at the top of the Session column

Indien je meer wilt weten over een bepaald protocol waar je veer verkeer over ziet lopen kan je op het protocol dubbelkikken, vervolgens krijg je te zien welke commincatie naar [destination] gaat:

 Notice what the active filters are displaying in the Status Bar

In folder C:\Documents and Settings\Administrator\Application Data\FirePlotter\ staan logbestanden aangemaakt door Fireplotter. Denk aan connectie logs en firewall configuratie.

 

Meer informatie: http://www.fireplotter.info/content/view/44/51

Download trial: FirePlotter Version 1.41 

Training video: FirePlotter Training Video – 3 minutes

Cisco:“Authentication failed” na DNS security update 953230 (MS08-037)

February 17th, 2009 No comments

Kan zijn, bijvoorbeeld vandaag in het geval van bij een klant, dat de Cisco VPN niet meer werkt met de melding “authentication failed”.

 

Na controle van de PIX alsmede de server blijkt dat op de server de Internet Authentication Service was gestopt.

 

Dit problem zal zich vaker kunnen voordoen omdat het ontstaat na een security update van Microsoft:

DNS security update 953230 (MS08-037) http://support.microsoft.com/kb/956189

 

Oplossing is een aanpassing in het register:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters

Daar de key ReservedPorts aanpassen door de poorten van IAS toe te voegen:

1645-1646

1812-1813
