To exit the menu without rebooting the switch, press the Menu button again.Select the SYSTEM REBOOT option and press the Enter button.When the MAIN MENU (Maintenance menu) appears, press the Enter button.From the LCD front panel menu push the Menu button.To restart the switch from the front panel: This command will also notify other users connected to the switch about the operation and will restart the device in one minute. Disconnect power from the switch by pulling out the plug end of the power cord connected the power source outlet.For information about the request system halt command, see the Junos OS command documentation.

Wait until a message appears on the console confirming that the operating system has halted. On the console or other management device connected to the switch (to the primary switch in a virtual chassis), enter the CLI operational mode and issue the following command to shut down the switch software: request system halt This command will also notify other users connected to the switch about the operation. Use the CLI command request system power-off from operational mode, which displays a message to the CLI, then disconnect the switch from electrical power. So in my opinion the problem definitely lies in the physical switch, not the virtual one.The information below describes the recommended method to safely turn off, halt, or restart the EX-series switch. Still only one switch is affected, the other one is working fine. If i move the dhcp server to esx1, the problem is solved there and starting on esx2. So the dhcp requests from machines on esx2 would not even have to leave the virtual switch. Now i realised, why the problem is only happening on esx1: the dhcp server for these machines is a vm, placed on esx2. Get-Virtualportgroup|select Name, VirtualSwitchId, Key, VLANId, VMHostID The problematic host is host-1002, the problematic nics i identified are vmnic4 and vmnic8, the port groups where the problem was observed are PortGroup35 and PortGroup41 Get-Virtualswitch|select Name, ID, NumPorts, NumPortsAvailable, Nic, MTU, VMHostID Since the visual config of our switches is too large for the screen, i did an export of the virtual switches and portgroups via powershell.
Reboot cisco switch upgrade#
Has anyone seen a behaviour like this? I am going out of opptions - soon we want to upgrade to ESX 6, but since we do also have VMWare View Desktop Virtualisation, the upgrade process will include a lot of work and testing and can't be done quickly. It seems to me as if this switch is somehow blocking access to the dhcp service. The result was: the problem only occours on two different ports on two different nics, but they are both connected to the same switch. I was then testing if the behaviour was connected to the physical part of the network: i removed all physical nics but one from the portgroup with the affected vlan, did some reboots with a dhcp machine, and then tested it with another nic - in short i forced all the traffic from this port group to go through one physical port of the nic and the switch. After that i even get positive results from dhcp explorer. After that i can move the machine back to esx1, and it will work perfectly fine. Now i have to migrate the machine to esx2 and wait for some time (or do ipconfig /renew or disable and enable the nic) the machine will get a dhcp address.
Reboot cisco switch manual#
When i reboot a vm, placed on esx1 and with automatic ip address configuration, the machine won't get a DHCP connect - the network connection is available, if i set a manual ip address everything works fine, but pconfig /refresh is haning, and DHCPExplorer does not find a valid dhcp server (which i can ping if i assigne a manual ip address). I am using 2 virtual switches (on each host), each switch has assigned The physikal networking is completly redundant, one of two switches AND one of two network cards on a server can fail without crashing the VMs. The switch (Cisco 2960E and 3850E) ports connected to the servers are configured with the cisco trunk vlan - all packets arrive with their vlan tag. The hardware is HP D元80 Gen8, 8 1Gb eth-ports. Our company network has multiple vlans, from which about 10 are needed in vm servers. We are using an Essentials licence, so we do not have distributed switches. We have 2 ESXi 5.5.0 build 2718055 in a cluster, managed by vCenter. We are having a strange behaviour in our ESX-cluster:
