Recently, I came across a port mirror issue of packet loss when mirrored traffic exceeded 5Gbps in a 10Gbps stack system.
The topology looks like this:
2 switches are stacked together as a single stack system and stack link speed = 10Gbps.
Traffic in one port of S1 is mirrored to another port in S2.
When test is performed, when traffic >5Gbps, there is packet loss.
After debugging, I discovered that the reason is that the original traffic also travels through the stack link between S1 and S2. Therefore, together with mirrored traffic, the link was saturated. And that's why packet loss was observed.
As a lesson learnt, please check other traffic going through the same link that carries mirrored traffic to make sure the total sum does not surpass the link rate limit to avoid packet loss due to congestion.
Hi All, I am creating a new user with privilege level of 15 on my ASA using the ASDM client. When, attempting to authentication using SSH and a password for the SSH session (note: no keys are installed), I receive the following error, indicating an i...
The goal is to use the router to terminate two wan connections for two separate networks, use the router for ip blacklisting, terminate vpn site-sites, and pass the accepted traffic to the ASA for further processing. I tried the RV-340, but I could ...
I have an RV340W (firmware 1.0.03.17) and a USB730L. The combination works mostly fine, except that it freezes at random during periods of large transfers (sometimes "large" is defined as 10 megabytes in 5 seconds). There seems to be no rhyme or reason to...

I have never played with Private VLANs. I have an SG300. All ports are in VLAN 1. The switch is connected to the inside interface of my ASA5505. I have a work laptop and it seems that the IP addresses from my work VPN a...
