• HP DL380p G8 - packets ignored on the management port but not the virtual computer.

  I searched through discussions, but not found a request for my problem.

  We have added two new guest VM in the center of the customer data. Currently, they had 2 x DL380 of the G7 which worked perfectly for 2 years. We have added two new DL380p G8 and have some weird dropouts on the management ports. Currently using SAS-store data (no SAN or iSCSI)

  I have pre configured servers (2008 R2 on each single guest) before their move in the data center using ESXi 5.0.2 http://h18004.www1.hp.com/products/servers/software/vmware/esxi-image.html HP installation. Since we moved to the datacenter, however, the new servers to experience about 10% loss/fall of package to the management port IP, but 0 packet loss on the IP comments. It doesn't make a difference either if the management port and the vswitch are on separate NIC interfaces, same result when combined on the same network adapter.

  The Guest VM seem to work well and are not affected by the present, but any P2V we are trying to do currently fail due to loss of packets on the management port.

  Other host (DL380 G7) servers running the HP exsi distro 5.0.0 and don't suffer these questions.

  Any advice would be appreciated. I wanted going 5.1 because when I was configuring initially I wasn't aware that there was an application of conversion of VMware for him - it seems now exists, so if you think 5.1 is the answer, then I'm happy to go ahead and do it.

  I solved this problem, but thanks for all the help...

  Note for all the other people there. If you clone an esxi installation SD or USB or else save time, the MAC addresses of the server of origin met on the new server, regardless of the different physical MAC address.

  To resolve I had to run esxcfg-advcfg - s 1/Net/FollowHardwareMac on the server that had double MAC address list.  All the VMnic (4) in both servers had the same Mac as well just change the port not fix her. A new card would have solved my problem, but does not solve the problem.

  The problem was discovered running by displaying the ARP table.

• How do the 4000th Equallogic Installer management ports

  Hello

  We released Equallogic 4000E with two controllers. I would like to connect the management ports on our "management VLANs" society.

  But I don't know if I need two different IP addresses for the two management ports?

  Or I just organize just one IP address for one of the ports management and EQL will take care of the rest? I understand that a single controller is active at a time.

  Appreciate any clarification on this if you have storage EQL.

  Thank you

  But what I don't understand is the number of IP addresses do I organize for the "management interface."

  1 single IP on your network.

  The standby controller will have all the IP when it become active (and the other become Eve).

• vMotion works only in a switch and the management

  Okay, I reconfigure my network in all of my 3 guests. I had vMotion (via VLAN50) in a vSwitch dedicated using binding rising vmnic0. vMotion between hosts has worked well. It looked like this...

  

  I want to spend vMotion for a vSwitch shared with the management network. So I deleted the vSwitch2 vmnic0 and added to vSwitch4. Then, I created a new port group for vMotion with a new IP address. See below.

  

  In vSwitch4 properties, the management network has vmnic7 as active and vmnic0 as the day before. vMotion is set in front of it. The vSwitch is configured to load balance from the originating virtual port ID.

  vMotion does not work between hosts and gets stuck at 14%. I get a timeout between 10.10.50.70 and 10.10.50.71 (another host).

  I don't know that my physical switch is configured correctly. I have two ports accepting traffic on the management and vMotion VLAN. If I pass around the allocation of vmnic (sort of management use vmnic0 as active and vmnic7 as before) then I can still ping the IP management. Also, if I move back to vSwitch2 vmnic0, vMotion starts working again so I guess I'm missing something on the side of ESXi.

  What Miss me?

  Thanks in advance

  OK, problem solved. The webex engineer had in my screen and start troubleshooting this.

  First of all, vmkping he had the IP address of the new IP address of vMotion to another host, that has failed. Then, he ran 'esxcfg-vmknic - l' and noticed that the old port vMotion group was always enabled. In the graphical interface it has disabled this by going into the properties of the vSwitch2 > vMotion port group and checked the property of vMotion. Then run vmkping, but it has always failed. Back in the GUI, he removed the vSwitch2 completely. Ran vmkping and it worked.

  He assumed the problem was vMotion was trying to communicate through the old switch, in spite of remove me the adapters and the engineer vMotion traffic on the port group in this deactivation switch. It is useless for me to keep the old vSwitches, except as a back fall where vMotion failed. Seems I should have been more courageous and just removed them when I was creating the new vSwitch.

• Vertical shift in the management interface?

  Hello

  On the PS6110, I know that this vertical failover works fine on the eth0 interface (10 Gig iSCS).  I tested several times and when I unplug eth0 on the (generally CM0) active CM, iSCSI traffic crosses to eth0 on the other CM (i.e. CM1).  Works very well.  However, when I unplug eth1 (management, 100 Mbps copper interface), failover to the interface on the other CM eth1 does not seem to occur.  Is it normal?  Is there a way to allow vertical failover for the management ports?

  Thank you

  Bill

  Hello Bill,

  No, h/s does not support that.  You will need to connect the two ports of Mgmt.

  Kind regards

• The managed behind router switch remote access?

  What is the best way to access remotely to a switch behind a router?  I will use a switch SF300, and there is no server.

  For points of access (PA) behind a router, I give each a diffferent LAN address and port number.  In router I have forward TCP traffic with the single port/LAN IP.  Then using the port numbers with the address of the static router, the browser can remote access to the router or the attached AP.  But where do I put the managed switch LAN port number?  Assume default is port 80 and I would change to 8001 to switch #1; 8002 to switch #2; etc.  Could not find this info in the manual of configurtion.

  Hello

  At this point, I would recommend a call to the Cisco Small Business Centre at 1-866-606-1866 support so that action can be taken and your configuration can be reviewed.

  I have reproduced the concern here and I am able to remotely manage my switch SF300 with an RV082 as the router.

  My rule in the RV082 are as follows:

  Creating a custom topic UPnP service.  Create SF300 application name (it is a basic text field and can be any name), 8001 an external port and internal port 80.  I send to the address IP internal SF300 switch and click the check box.  From there on, I select Add to the list.  Once it appears in my list, I then click Save settings at the bottom of the page.

  Thank you!

• ESXi 3.5 - Management Port now a Vmkernel Port

  I built my first box of ESXi 3.5.  Wow I love the installation.  Had a working server complete in less than 15 min from start at once, as it was in the CR 2.5.  After installation, I noticed when I went to add a new vswitch so that at the end of the wizzard I wasn't able to create a port vmkernel on the same subnet as an another port of vmotion vmkernel.  I watched one noticed that vswif (vswitch0) did not have a console port.  The management port has been merged/rolls in a way vmkernel.  I checked a TI has the ability to make a port of vmotion.

  My question is... Is this OK or best practice or not a good idea to use the vswitch hosting the management port to get the vmotion traffic using ESXi?

  Pete

  Hello

  Transferred to ESXi forum.

  My question is... Is this OK or best practice or not a good idea to use the vswitch hosting the management port to get the vmotion traffic using ESXi?

  I would treat the management port just like you would treat any network management, keep it separate. However, most people combine VMotion and management on the same vSwitch.  In general from a security perspective, the management is separated from VMotion. VMotion is a clear text Protocol, so access to it should be restricted to JUST ESX hosts.

  If it was me, I create an another vmkernel for VMotion on a different subnet, and give it it's own Teddy.

  Best regards

• IPS detects not not malicious traffic in the outbound direction

  I have an IPS running 4240 6.0. I have an interface in promiscuous mode which is connected to a port which LASTED on the uplink of a switch to my router. I'm doing some tests and noticed that when you use nmap from a host inside a host on a remote subnet, which requires me to send my traffic via the uplink port across the interface that the IPS is followed in an outbound direction, no signature is triggered. However, if I do the scan even reverse the location of the perpetrator and the victim, so the scan comes entering the detector immediately picks up the scan and triggers the appropriate signatures. Why would this behavior occurs and is at - there a way to change this?

  The other fire signatures on "outgoing". Nothing at all?

  The first thing that came to mind is that you could have extended only together as your destination span port is only to see the of receipt and not the transmission traffic. It's only a guess because I don't have all the details here.

  Before we can really begin to consider why, we need some details.

  Which switch model (in which case there is a limitation to the span config).

  What is the span config.

  How are you running nmap (what are the options).

  What alerts are triggered for you on the reverse.

• About 4500 X VSS question management port

  I have two switches of 4500 autonomous X that I intend to convert vs. If I cable to the management port on the two switches for a cloud of management, what management port should be the IP address of management? It is the active switch port? If the active switch failed, the management of the standby switch port would resume the IP management?

  The management port is VRF mgmtVrf. Should I create a default for the VRF route ' ip route vrf mgmtvrf 0.0.0.0 0.0.0.0... ' to point to the IP Address of the default gateway?

  Thank you

  When you convert the VSS chassis, only the interfaces of management (FastEthernet1) for switch-1 (active) will be visible in the config.  If you want both your cable management cloud management interfaces, but you apply only the IP address to the active switch.

  The management port is VRF mgmtVrf. Should I create a default for the VRF route ' ip route vrf mgmtvrf 0.0.0.0 0.0.0.0... ' to point to the IP Address of the default gateway?

  OK, you need a default route in the vrf mgmt pointing to the bridge.

• How do the management interface of configuration of an ethernet interface?

  We have an ASA 5540 requiring a LAN port for failover. And the left side of the interface available only the management port. How do the management interface of configuration of an ethernet interface?

  You can disable the mode of management only on this interface to make as regualr routable port and use for other purposes, including the purposes of failover LAN database.

  On the management interface - 5510 but applies generally to the management0/0, itself including 5540

• ESX 4.1 management port

  Hello

  I have 1 NIC and my host network interface was working on IP 192.168.10.1 and is the network management from the beginning, when I installed VMware ESX 4.1, when I change the management port to the vlan 1 is not accessible all the network connection are OK when I'm trying to ping from the same subnet, it does not ping. Even though when I plug directly into a laptop ESX hostby is not ping, NOW what are the steps I need to take to recover the host.

  Thank you

  You must activate shell access through the console of the ESXi host - instructions can be found in this doc - http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-command-line-interface-getting-started-guide.pdf - once you remove the tag of vlan of the vwitch - http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-command-line-interface-solutions-and-examples-guide.pdf

  Or you can change the physical switch and add the id vlan to the port.

• WRT350N configuration based on the web does not load on the cable port.

  I've had this router for over 6 months, and only in the last two weeks, I could not access the configuration page based on the web through my PC, connected to one of the 4 wired ports. None of the laptops I tried (Win XP, Vista) are connected via Wi - Fi without a problem. Obviously, this isn't an emergency, because I can access it through the laptop, but I use mostly my PC to manage the router.

  Any ideas on other things to check?

  Thanks for the tip, but that did not work... However, trying to fix another problem, with the USB port of a storage drive, I re-load the updated firmware and am now able to access the configuration page. Still no action on the USB key if!

  Thanks again!

• There is a security risk to plug the internet router management on the LAN port?

  I have to install an ASR1001 on the internet for my business.  I noticed that the ASR1001 has a dedicated management port and I was wondering if it's a security risk to have this mangment port directly connected to my local network, so that I can mange it from my office.

  I want to only run the ASR of this port and I will no management through its public IP address.  Is it possible for a malicious user to compromise the router then have access to the network but this management port?

  I'd say it's a reasonable risk.  If you intend not to allow future management of the public side sessions you are a good start, implementation of protection against attacks.  Combine that with a few basic hardening, for example to disable source routing, directed broadcast, ip proxy arp, finger, as well as an ACL on the management interface so that all traffic from an untrusted interface on the router would be unable to receive return traffic.  In addition, the management vlan must be a dedicated vlan.  I would not fall in the same vlan in that your office is located.  Better design would be to fall into a dmz (acl on the router's management interface would be redundant in this case) and to apply the rules of the firewall.  However, if this is not possible, order access to routing on the ASR as well by including only a 32 road to your management station via the management VLAN interface.  Also, remove any redisribution or advertising of this management interface in your routing protocol.

• Use of the Trunk Ports (Cisco) on the management interface

  Hi all

  Background:

  We are in the process of consolidation of 2 farms of esx servers and will end up with 10 guests in a single cluster. Guests come from 2 VLAN separate (say 10 of VLANs and vlan 20). A test I took one of the hosts of HA/DRS and tests with it. For HA and DRS to work efficiently and properly in common all resources, we all want vm to leave both VLAN access to move to any host in the cluster.

  The test:

  My single host mentioned above, I created 2 groups of ports on a vswitch, vlan10 tag and with vlan20, I deployed a VM and tried on the two IP address ranges. It worked (with the correct settings of defined IP by VLAN) but as soon as we resources shared the port used by the management of network vmkernel port we lost the connection to the HOST from a management perspective. What the question is that it is possible to connect the management network a trunk port? We have 2 network interfaces connected to the vSwitch and both used for the VM traffic as well as management traffic. That's how they are currently implemented except that the switch port is on a VLAN-specific rather than shared resources.

  Thank you very much

  Chris

  Hi Chris

  Yes, the network management also accepts the vlan tagging/trunking.

  Just add the number VLAN on the Portgroup.

  Maybe you can do a printscreen with the current configuration?

• Running the software iSCSI on a different subnet than the management traffic

  I hope I'm missing something obvious you smart people might be able to help with.

  I am trying to put in place a small instance of vSphere using ESXi 4.0 Update 2 and unlike most of our environment, we use the iSCSI instead of fibre SAN storage.

  The intention is to set up a network on subnet A, for management and Vmotion traffic which will have 2 natachasery attached.

  We have a second 'B' allocated for iSCSI storage subnet and have 2 separate natachasery which will be implemented through two vSwitches, 1 Teddy for each.

  We have implemented the switch management/vmotion on a subnet and, of course, the default for this subnet gateway entry when asked.

  The iSCSI subnet naturally has a different gateway and so when I entered IP address on subnet B in the port of core, it seems always trying to route through the gateway to subnet an attack to storage not being is not visible.

  We have verified that the problem is not with the storage or the ESXi put in place by proving that if we give the iSCSI port IP subnet A (and also the storage) then we can see storage without problems - simply, the question seems to be everywhere to try to operate on a completely isolated subnet.

  Isolation of storage traffic is a customer demand, and not something that we cannot ignore.

  Anyone know if it's possible (and if so what should I do to solve the problem) OR should we look for to move to ESX Classis and use his ability to use 2 different gateways?

  I feel that I must be missing something pretty obvious I don't know there must be a way to achieve segregation of traffic on subnets for the other core activities such as vmotion, fault tolerance and management traffic.

  There is only one door of entry for VMkernel, then you can separate VMotion / iSCSI / fault tolerance than if not routable subnets, i.e. all hosts on the same subnet.
