The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Cisco switch management configuration

Asked by David_Bell20 in Network Management, Network Operations

Tags: Cisco, default-gateway, ping, management

I have a Cisco 2940, which is connected via a trunk to a 3750, which in turn connects to the core switch.
I have a need to change the management address and vlan on the switch, from the default '1' to 999.

As is normal the switch is uplinked via a trunk interface, the trunk has a native vlan 999 and can be managed remotely fine when configured with an IP address in vlan 1.

However when I change the default-gateway to the gateway address of vlan 999, configure a vlan 999 address, and do a no shut, I can not ping out at all. VTP is distributing vlan 999 fine, it is not blocked in the trunk and I know the default-gateway address is good - I can ping it from my PC - any ideas?

interface GigabitEthernet0/1
 switchport trunk native vlan 999
 switchport mode trunk
 
I've been trying to configure the trunk for dot1q, however have the following:
SGH09-NetworkServi(config-if)#switchport trunk ?
  allowed  Set allowed VLAN characteristics when interface is in trunking mode
  native   Set trunking native characteristics when interface is in trunking mode
  pruning  Set pruning VLAN characteristics when interface is in trunking mode
 
dot1q is not selectable.
 
However with the above configurations, and vlan 1 IP address configured I can remotely manage the switch fine. If I then change the management address to vlan 999, and set the relevant defaul gateway - I can not ping in or out.
 
Hope someone can help!
