• ESXi - Trunking for Cisco switch

  Hi, I'm having a little trouble to create a trunk to a crowd of v4.1 ESXi.

  My config on the switch

  interface GigabitEthernet3/29
  switchport trunk encapsulation dot1q
  switchport trunk allowed vlan 100 300
  switchport mode trunk
  switchport nonegotiate
  spanning tree portfast trunk

  ESXi side VLAN ID has been set to all (4095) - side switch and host configurations is passed to the host of vCentre.

  Defining the interface of switching on an access on VLAN100 port, the host will stand fine. Problem is that I need another network to be consulted (VLAN300)

  interface GigabitEthernet3/29
  switchport access vlan 100
  switchport mode access
  spanning tree portfast
  end

  I am able to allow a second card on the host computer and the whole upward like a trunk as above, seems to work fine, even if I don't have a virtual machine upwards on it yet to test

  *

  My query is, how can we allow multiple VLANs to an ESXi host on a single card? What I'm missing here...

  Thanks in adavance.

  Brendan

  For me, looks like the vmkernel interface used for the management network is not be marked, as the host responds when you define the physical switch as an access port port in the VLAN 100. So either mark the vmkernel with VLAN ID 100 port or VLAN 100 native VLAN on the switchport physical... (switchport trunk vlan 100 native)

• 10G Cisco switch

  I would like to know if the compatibility for the storage matrix Dell is updated regularly, especially for cisco switches.
  We seek to deploy a few PS6210 with 10G connectiivity and here for use with switches Cisco 4500 X series. However these are not included in the doc. There are a few cisco switches that are the end of life (4948 and some nexus switches).

  Hello

  Yes the guide is updated regularly, usually monthly or updates are available.

  Since the x 4500 is not a Nexus series switch, you looking for correct DCB support?

  In this case these Dell 'Level 3' offers better support for resonable effort.   I'll make sure that use you the latest firmware IOS and EQL.  There are other switches catalyst IOS in the guide.  Configure it in this sense would be a great place to start.   Ideally, the switch dedicated for iSCSI use, not VLANd with other types of traffic.

  If you can first test before production, then support can see table diagnosis and SANHQ archive for any signs of network related issues.   (retransmit rate and types for example)

  Kind regards

• Plug-and-Play for Cisco Small Business 300 Series managed switch

  Nice day

  What are the automatic installation options available for the Managed Switch series of Cisco Small Business 300?

  It seems there are not, the operating system is not the standard IOS I used to.

  I would use with ability to bridge the Infrastructure first Cisco PnP.

  Concerning

  Stone

  First Infrastructure use and assume an agent CNS (Cisco Network Services) on the other side, when you enable the 'plug & play '. Series 300/500 do not run IOS and does not include the CNS agent, but there is a way to activate the automatic configuration. Switches supported by the automatic DHCP configuration (using DHCP options 66, 67, etc.) in which case they automatically download their config to a TFTP server at boot time. This allows an administrator to put the configs for all switches on a TFTP server and simply start a default switch factory in order to obtain config.

  Seal a document shows how this is done.

  Hope that the information would be useful.

• Required for NAC firewall ports manager manage/add the Cisco switch

  Hello

  I am trying to add switches cisco for the NAM, but I am not able to add the switch I get the error "unable to control switch" I tried opening ports 161-162 on the firwall; If I were to allow all traffic between the NAM and the switch, cisco NAM is able to add/manage the switch.

  Do not know what are the other ports may be required for cisco NAM for managing the switch?

  Thank you.

  Hello

  As far as I KNOW, only UDP 161 and 162 for SNMP communication ports must be open.

  Please make sure that you have configured the correct port on the switch:

  (config)# snmp-server host 172.16.1.61 traps version 2c cam_v2 udp-port 162 mac-notification snmp 

  If still does not, I would check the logs on the firewall for any traffic blocked between the cam and the switch.

  HTH,

• Compatibility matrix for Cisco Catalyst 3012 Switch Module

  Hello

  I'm checking the compatibility of the VMware vSphere 5.5U1 Guide and an IBM switch module Part Number: 43W4401 product name: Cisco Catalyst Switch Module 3012. The search of the matrix returns Cisco 1GigE I350 LOM who seems to identify the drivers of Cisco.

  Can anyone help clarify and check if this IBM re-branded chassis switch module is supported and to a specific firmware for the switch code? Thank you all.

  L2/L3 switches are off-limit of drivers for vSphere hypervisor, so you don't find on the HCL...

• Configure the VLAN voice and data in CISCO SF 300 8 P

  I have a couple of Cisco SF 300 8 P and P 24 switches. I have voice and data VLANS configured as:

  Data VLAN: default 145.17.59.0/24

  Voice VLANS: VLAN 20 172.22.20.0/24

  I have different DHCP servers regarding the data VLAN, we have a physical server that is configured for 145.17.59 * extended IP and Voice VLAN DHCP Server is configured as a router gateway with option 150.

  This configuration works very well with other cisco 2960 switches and 3750 etc. except CISCO SF 300 8 P and 24 p. I tried to set up the voice and data VLAN in these CISCO switches so that phone CISCO (model 6941) should get IP of the VLAN voice and PC should get the IP address of the DHCP server on the data VLAN. I tried several techniques such as LLDP, Port-to-VLAN Config etc.

  Can anyone please guide me / help on this.

  Kind regards
  A K.M.Sayeed

  Hi A.K.M., with Cisco phones you should be able to define simply automatic voice VLAN to be VLAN20.

  ID of the vlan 20 voices

  You must ensure CDP or LLDP is enabled as well. I would check in the web GUI. DHCP for phones can come from a DHCP server on a port access VLAN20 switch, or you can use dhcp for assistance to redirect DHCP server elsewhere.

  If you prefer or you have problems with the CDP or LLDP, you can also program the ports as trunks and add the tag VLAN 20 for them.  In this scenario, you need to ensure inter - vlan routing works and phones that download the file config with corrrect VLAN config.

  These switches do not run ios, so they are similar, but different from the catalyst switches that you mentioned.

• Configuration Wireless 3G as online backup with cisco switch layer 3?

  Hi all

  We have an existing GPRS modems for data transfer between 2 different sites, this connection is a bit slow to no more than approximately 114 Kbps, the idea is to add a 3G modem, so the solution will be based on a two-way communication lines which are 3G network and the GPRS network.

  The line GPRS will be the main and 3G will be secondary, this redundancy offers a high level of availability of communication between the two sites.

  is it possible to configure this redundancy with a cisco switch layer 3? If this is the case do you have a tutorial or a link which explain how to do this work with a layer switch 3 ciso?

  all information will be useful for me, thanks

  Hello

  The config is one provided by anisaini, but you need to change your NAT like this:

  IP nat inside source MAIN interface map route x/x main interface

  IP nat inside source route-map interface o/o interface secondary SCHOOL

  Interior int z/z interface

  IP nat inside

  int x/x

  NAT outside IP

  int y/y

  NAT outside IP

  access-list 99

  permit x.x.x.x y.y.y.y where x.x.x.x is your home subnet addresses and y.y.y.y is the corresponding generic mask

  PRIMARY route map

  match ip add 99

  match interface x/x

  SECONDARY route map

  match ip add 99

  game interface y/y

• Reference Dell OMSA Release Date for vSphere 6.0 ViB

  Hello

  information about the release dates for vib for vSphere vsphere 6 (OMSA 7.4.1 / 8.0.1 / 8.0.2)

  Apart from that... OMSA 8 will continue in two different development branches for T630, R630, R730, R730xd and T430/R430/T530/R530/M630... or will it be a next single version for all serversystems of 13 G.

  Kind regards

  Torsten

  Toki76,

  Custom Dell ESXi ISO 6.0 came out 2 days ago. So I guess, from past experience, that the VIB is going to be released very soon behind him, but at the moment I do not see that he launched. I can research to see if I can refine the delivery date well and let you know.

  What about OMSA 8, probably a single version which includes the two branches.

• Why I can't command show running on cisco switch

  OK, so the information you provided in your latest messages confirm that the privilege level you get via telnet/vty is different from the one you get via the console. This is due to the configuration of AAA which applies to the vty ports but not on the console port.

  So if you want the same rules apply to the console port, then you must configure the port console for AAA as well.

  If you don't want these rules then you need to remove the AAA configurations. The best way to remove these is by typing 'no new aaa - model' However, careful not to lock you out of the unit. Make sure you have local accounts with the privilege level 15 and you also know the active password/secret.

  I hope this helps!

  Thank you for evaluating useful messages!

• To the main unit Infrastructure Cisco switch port

  Hello.

  I had a doubt as to the Port of the Switch in my Cisco Switch for a camera of the first Infrastructure.

  This port must be a Switchport to access or a Switchport Trunk?

  What is your recommendation on this subject? What is best practice?

  Thank you very much.

  Access port should work fine. You do not configure a VLAN on the device itself, just the IP address / subnet and default gateway.

  Thank you

• Switchport security best practices for Cisco IP phones

  Hello.

  I have some difficulty to understand what the safest method is to ensure a Cisco IP Phone.

  Can't get info on how many course connect a switchport and a telephone computer IP Cisco with a daisy chained to him.

  The thing I fear more precisely is how to secure against attacks of Double VLAN tagging and COP on this port.

  I searched regardless of the possible resource for the answer and you have not found anything useful.

  I also have a question regarding port security on a switch: can you set a minimum amount of MAC addresses active and then limit the period of ageing on the MAC addresses on a specific switchport, such that if someone disconnects the phone and sets up a Cisco switch or other device of thugs, then the port should be stopped during the period of ageing.

  Let me know, what you would suggest to better secure the hose between the Cisco IP phone and the switch.

  Best regards

  Casper.
