Hi,

 

I'm not verse with networking but I'll try to help out. It may seem that the VLANs are not able to communicate with each other. IP routing show be able to enable them to communicate. Would you mind checking if the IP routing command is configured in global setting?

Thanks for replying.

I've just run though the examples in the manual (pages 212-213) using the following commands in the CLI.

 

console(config)# ip routing
console(config)# vlan database
console(config-vlan)# vlan 100
console(config-vlan)# vlan 150
console(config-vlan)# exit
console(config)# interface vlan 100
console(config-if)#ip address 1.1.1.1 255.255.255.0
console(config-if)# exit
console(config)# interface vlan 150
console(config-if)#ip address 2.1.1.1 255.255.255.0
console(config-if)# exit
console(config)#interface gi2/0/1
console(config-if)# switchport access vlan 100
console(config-if)# exit
console(config)#interface gi2/0/2
console(config-if)# switchport access vlan 150
console(config-if)# exit

 

I then connected 2 pcs to ports 1 & 2 and set them as
PC1 : Port 1 IP 1.1.1.2, Gateway 1.1.1.1
PC1 : Port 2 IP 2.1.1.2, Gateway 2.1.1.1

As per my previous attempts (with different ips)> Each machine can ping all the interfaces on the switch (1.1.1.1, 2.1.1.1, 192.168.0.246, which I left on the default vlan for access).

But they cannot ping each other. 
A tracert from PC1 to PC2 shows

 

Tracing route to 2.1.1.2 over a maximun of 30 hops
1  1 ms   4 ms   4 ms  1.1.1.1
2  *      *      *     Request timed out.
etc....

 

I think this means that it's not routing between the vlans inside the switch, i.e. no route between 1.1.1.1 & 2.1.1.1

Looking at the routes on the switch shows

 

console# show ip route
Maximum Parallel Paths: 1 (1 after reset)
IP Forwarding:          enabled

Codes: C - connected, S - static, D - DHCP

S  0.0.0.0/0          [1/1] via  192.168.0.1  0:33:7               vlan 1
C  1.1.1.0/24         is directly connected                        vlan 100
C  2.1.1.0/24         is directly connected                        vlan 150
C  192.168.0.0/23     is directly connected                        vlan 1

 

Which is where my (limited) knowledge runs out as I have no idea what any of that means.

So still stuck

Hello @darious1472,

 

Maybe there is an issue on the VLAN database. It could not have been created. Could you check this article: How to create VLANs on a Dell Networking PowerConnect Switches
- https://dell.to/2QkEtWt


Regards.

I'm quite sure it's created the vlans. I can see them in the Web UI and

console# show vlan

Vlan     Name        Tagged Ports      UnTagged Ports     Type    Authorization

                                     te5/0/1-2,
                                     gi6/0/1-48,
                                     te6/0/1-2,
                                     gi7/0/1-48,
                                     te7/0/1-2,
                                     gi8/0/1-48,
                                     te8/0/1-2,Po1-32

150      150                              gi2/0/2       permanent   Required

which looks like vlans 100 and 150 are there.

Hi,

 

I'm pretty sure you mentioned you followed the user guide page 212 on the commands. Though, would you mind, doing the configure again after you have cleared the previous configuration, but following this method:

 

console#config

console(config)# vlan database

console(config-vlan)# vlan 100-150

console(config-vlan)# exit

console(config)#interface gi1/0/1

console(config-if)# switchport access vlan 100

console(config-if)# ip address 1.1.1.1 255.255.255.0

console(config-vlan)# exit

console(config)#interface gi1/0/2

console(config-if)# switchport access vlan 150

console(config-if)# ip address 2.1.1.1 255.255.255.0

console(config-vlan)# exit

 

Test the ping, and let us know the outcome. 

April 14th, 2021 01:00

I just tried the above, .i.e. reset the switch then did...

console# config
console(config)# enable password ***
console(config)# vlan database
console(config-vlan)# vlan 100-150
console(config-vlan)# exit
console(config)# interface gi1/0/1
console(config-if)# switchport access vlan 100
console(config-if)# ip address 1.1.1.1 255.255.255.0
console(config-if)# exit
console(config)# interface gi1/0/2
console(config-if)# switchport access vlan 150
console(config-if)# ip address 2.1.1.1 255.255.255.0
console(config-if)# exit
console(config)#

That appears to be worse.
the two pcs attached to ports 1 & 2 still cannot ping each other. They also cannot ping any of the interfaces on the switch

Hello darious1472,

What is the current version of firmware that is on your switch?

I am not able to see the output reply display on your post comment. Would you be able to PM me the output results.

didn't like having the service tag in there.

Yeah, with the dhcp server enabled on the switch and the ip address pools set to the correct ranges. The PCs on ports 1 & 2 were being assigned suitable IP addresses and had the relevant switch gateway address set for each vlan.

i.e. PC1 on port 1, VLAN10 was given ip 192.168.10.1 and had 192.168.10.246 as the gateway address, which was the ip assigned on the switch to VLAN10.

Hi,

 

Thanks for the output. I might need to check it and need some time to find out what's the issue. 

 

Meanwhile, could you check if the PC connected to the port 1 and 2 are getting IP assigned?

Hi,

What is the output of show ip route? Try turning of ip routing and turning it back on again.

no ip routing
