Help!!! Redundancy on Switch Layer 3 using VTP + STP + HSRP

JackyHo · ‎11-16-2018

I'm using Packet Tracer version 7.1.1 for my testing purpose before performing to the real device.

Network topology:

- Distribution SW1 (DLS1) and Distribution SW2 (DLS2) => same model Cisco 3650

- Access Switch (ALS1): model Cisco 2960

Experiencing issues:

1. Some link not blinking

Why the few link is not blinking? Any wrong config?

2. ICMP with high latency

ICMP high latency

3. HSRP is working not properly.

I'm stressing with it, I think something wrong configures but I still not figure-out.

I need someone to help me a favor to figure-out the root cause. Thanks.

See my Switch configure in the attached files.

Hello

What is your issue here? I am not able to open those files at present so cannot see the config?
Can you tell me if that link you are showing is a port-channel or a normal trunk/access connection?

Do you have separate hrsp groups for your vlans or just using the one group?

If you can post the packet-tracer file

Please rate and mark as an accepted solution if you have found any of the information provided useful.
This then could assist others on these forums to find a valuable answer and broadens the community’s global network.

Kind Regards
Paul

to clarify the setup you could

- enable port-names in the graphic

- set port-descriptions in the config

my guess is DLS1 and DLS2 are connected using Po1 (Gi1/0/23 + Gi1/0/24)

also ALS1 is connected using Gi0/1 and Gi0/2

but it is not clear if the links in the graphic are those ports.

on the ALS1 you possibly connect Gi1/0/23 + Gi1/0/24 to DLS1/2 and you configured a port-channel for this

but on the DLS1/2 the ports ar NOT port-channel

You cannot span a port-channel across two switches that are not stacked or VSS

please remove the "channel-group 1 mode on" in the ALS1 config
