Hi there, The CAB-C15-CBN has a 'notch' in the female end. They are used on high wattage PSU's. you will find a standard C13-C14 cable will not fit in the PSU.   cheers, Seb. ... View more

Hi there, @marce1000 suggestion is the correct one moving forward, but you can force the SSH client to connect by specifying the crypto parameters:   ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -c aes128-gcm -l admin 192.168.1.1   cheers, Seb. ... View more

Hi there, When you say nothing works, do you mean there is no comms between subnets when applied or that the VACL doesn't work as intended?   The permit ip any any you have at the bottom of MYXLIST ACL shadows the preceding ACEs and makes them redundant. I suggest removing the last ACE and let the implicit deny do its work and retest: ! ip access-list extended MYXLIST no permit ip any any !   cheers, Seb. ... View more

Hello again, This packet capture just shows encrypted traffic, it is not possible to diagnose the problem.   Is it possible to get the unencrypted traffic between the hosts?   cheers, Seb. ... View more

Hi there, Firstly, the output you provided is for a router with FastEthernet interfaces, not the GigabitEthernet interfaces specified in your original configuration. Also you indicated that Gi0/1 was connected to the switch, however it is Fa0/0 which is configured with the correct IPv6 prefix.   Assuming the above are mistakes....   The IPV6 configuration looks good, but the empty neighbour table is not so great. On the switch can you confirm that the switchports connected to the router Gi0/1 and the PC are on the same VLAN? Can you share the output of: sh mac address sh spanning-tree vlan <VLAN_ID_OF_SWITCHPORTS_CONNECTED_TO_GI0/1_AND_THE_PC>   cheers, Seb. ... View more

Hi there, From the router can you share the output from the following commands: sh ipv6 int gi0/1 sh ipv6 neigh   Can you call share the PC interface configuration: ip -6 address show <interface_name> ifconfig ipconfig   cheers, Seb. ... View more

Hi there, You hypervisor will have a construct called a vSwitch. This is connected to one or more physical interfaces on the server. The vSwitch itself will then have 'Port Groups' which are each assigned a VLAN ID. You VMs will then connect their virtual interfaces into the required Port Group giving you the required VLAN segregation. The vSwitch will handle the VLAN tags required for this operation. Of course you can also assign a single VLAN to a physical interface by having a separate vSwitch with a single Port Group and a dedicated physical adapter.   I should point out the above terms are from vmware, but the concepts should be the same across most architectures.   https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/techpaper/virtual_networking_concepts.pdf   cheers, Seb. ...
