Cant Ping My Switch

[WildMan365]

I am connecting a 3750 switch directly to another switch. The switch I am connecting to has vlan 1058 untagged on all ports and I can access the internet and ping the default gateway from it. It has no connection issues.

I have configured vlan 1058 on the 3750, disabled spanning tree on all interfaces/vlans, shut down vlan 1, no shut down vlan 1058/ interface & configured an unused IP and the correct default gateway on vlan 1058. I

I can ping it from my PC but the port goes down and interface vlan 1058 both go down after about 10 pings.

The syslogs were giving me errors and I adjusted configurations which allowed me to ping. I also enabled IP Routing but that didn't work. I even cleared the arp cache on the Core switch/router. I'm not sure what I'm doing wrong.  I'm just trying to get this switch online.

Hello

I am trying to understand what you have done again regards connecting the two switch together

The first switch is connected to i guess the router and all ports are a created vlan 1050, when you say untagged did you specify this vlan as native?

Not sure either what you mean by shuting all vlan/ports down ?

Can you post the config please ?

Here's my config. I disabled ip routing cause I'm am only trying to give a management IP to the device. I also disabled spanning tree on the upstream switch and can access devices fine from vlan 1058 with my PC. Again I can ping the switch & my pc which is on the same subnet/vlan only when I unplug the switch and reconnect it. And at that I get about 10 replys then it drops. The syslog shows interface vlan 1058 and Gi1/0/1 up/up then I can ping, then 10 seconds later the syslog shows them both go down and immeadielty back up. When they go back up I stop being able to ping the switch. When I first started configuring the syslog gave me VTP error for creating vlan 1058 which I fixed and spanning tree bpdu errors too which I also corrected. After those 2 corrections I was then able to ping but these are the results I'm experiencing now. This is a brand new switch by the way.

Hi

Verify the cabling or Network card on the computer. 

Also try

interface Vlan 1058
 ip address 10.222.58.5 255.255.255.0

shutdown

no shutdown 

Based on your comments it is a unusual situation, try to upgrade and if the problem persists a ticket with the TAC could be opened to discard any hardware/software problem. 

[paul driver · Accepted solution]

Hello

vlan 1050 is an extended vlan and you've disabled spanning tree which is a requirement for extended vlans when enabled.

[Julio E. Moisa]

Good point Paul, STP is disabled for Vlan 1 and 1058.

Spanning-tree should never be disabled. 

[WildMan365]

How do I enable it? Its not letting me (Switch(config)#no no spanning-tree vlan 1,1058) & also I could not ping it until I disabled it.

[paul driver]

Hello

spanning -tree vlan 1-4094
spanning-tree extended system-ID

Also it could be possible that your using a vlan number that is internally assigned by the switch in that case you need to pick one that isn't being used

show vlan internal usage

Thanks Paul! I disabled STP cause I got the following Log ....

*Mar  1 01:01:00.796: %SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk GigabitEthernet1/0/3 VLAN1058.
*Mar  1 01:01:00.796: %SPANTREE-7-BLOCK_PORT_TYPE: Blocking GigabitEthernet1/0/3 on VLAN1058. Inconsistent port type.

Adding STP did not work originally maybe cause the new 3750 is connected to another managed switch/port with vlan 1058 (untagged) & 2058(tagged) which may have inspired the syslogs above. I added the following to the interface/uplink & have been pinging for over 5 minutes now.

interface GigabitEthernet1/0/3
 switchport access vlan 1058
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 1058

[paul driver]

Hello

That error occurs when two connected ports are configured differently (inconsistent) ( 1 access and 1 trunk)

glad to hear its working now
