Hi all, After adding a 9800-CL to Prime I got a critical alarm. Does somebody know the reason for this? Catalyst 9800 Telemetry coral connection failure for device IP 10.1.51.11. Please check the coral connection. Many Thanks! Regards, Urs

The goal ist to build a fusion vrf. In the end each vrf peers with the fusion vrf through the transparent firewall. But first I wanted to test connectivity between the vrfs. Unfortunately I cannot reach the interface "behind" the firewall.

Hi,
I am trying to connect a transparent firewall to a N7k. Therefore I set up two interfaces E1/17 and E1/18 belonging to different vrf's and connected these ports together. I expected the interfaces would be able to reach each other. Unfortunately this does not work. Is my design supported or do I have to use a seperate VDC for this to work? I'd appreciate a hint for a solution.
Many Thanks,
Urs

Hi,
Thanks for your reply. There is no need for NAT. I agree with you, the easyest way would be replacing the old ISRs with new ones. From a cost perspective the 9300 would be attractive if they performed equal. Furthermore we could substitute the ISR and the existing Aggregation Switch with one device in each location.

Hi all,
As far as I know the 9300 supports gre. I am looking for a replacement of DMVPN. The network is built using ISR G2 which are going end of life.
The network consists of a redundant hub and 6 spokes. 7 VRFs are in use which connect through a dedicated mgre tunnel. There is no need of IPSec so I guess we could build a mgre network using Cat9300 instead of ISRs.
My only concern is abut throughput. With the old ISRs we got about 250Mbps throughput. Does somebody know about the gre Throuput of a Cat9300?
Many Thanks!
Regards,
Urs

Hi All,
After implementation of dot1x I noticed all Access Points were not visible in CDP anymore. Access Point on Stack Member1 are visible whereas those on Member2 are not. I also added Smartport Macros.
It seems configuration is not identical on both Member Switches. All Switchports on Member2 have CDP disabled and Smarport Macros don't appear in config. Is this normal behavior? I guess there is something wrong.

Thanks for your reply. Am I right that a backup of 2.2 can be restored in 3.4 then? That would be great.

Hi all,
I wonder if it's possible to skip the upgrade path through 3.0, 3.1 to 3.4. Backup of 2.2 can be restored in 3.0. Is it possible to restore a backup of 2.2 in 3.4 as well?

Urs

many thanks for the quick response. I have known about this command. I wonder why this happens and if there is a way to prevent it. I mean there might be a job on Prime for this cleaning tasks. Otherwise one has to perform the cleanup from time to time.

Hi All,
Our Customer is wondering why the backup file size is constantly increasing. From what I know there have been no changes on Prime or WLC.
I can not imagine that the log files have increased in such a huge amount.
I would appreciate any hints why this can happen.
Many Thanks!

Yes, it is a hospital. The Controllers are WISM2 with OS 8.0.132. We've only found clients on APs 3502 with this issue. Probably there are others as well but as the majority of APs is of type 3502 it is hard to say. I knew someone would ask about RRM. We decided to disable RRM in some areas. To be honest, areas without RRM work much better with spectralink phones. About a year ago we set up the WLC regarding Spectralinks Guide for Cisco WLAN. This setup was unusable. Phones did not roam smoothly, we had one-way audio, Phones were frozen and had to be rebooted ... After several Software Updates on Phones and disabling RRM in some areas we could eliminate nearly all issues. Just to clarify: RRM is not disabled. Only Channels and Power levels have been fixed in some areas. A site survey showed, that power levels with RRM were rather low in some areas.

Hi Rasika, I am going to ask the Customer to do a capture using Netmon. Unfortunately these issues are not predictable. They occur on different Access Points from time to time. Is there something other than RRM that could cause an Access Point to disassociate its clients? RRM is disabled. Many Thanks for your advice! Regards, Urs

Hi all,
we have the same issue and get a huge amount of log messages on a 4500x VSS. I am a bit confused. Has this really no impact and is it only a cosmetic issue?

This article exactly describes the behavior I can see. Pinging the Nexus itself results in Control plane policy drops. Pinging another device in the subnet does not cause drops as the traffic is not destined for the CPU. Nevertheless some ICMP Replies do not find the way back to the sender. My question is where to look for the reason for these lost packets.
