I am trying to monitor the spanning-tree status of my arista switches via SNMP. With other brands, that was quite easy:
188.8.131.52.184.108.40.206.5.0 --> Current root bridge
220.127.116.11.18.104.22.168.7.0 --> Port to root bridge
22.214.171.124.126.96.36.199.2.0 --> Priority
188.8.131.52.184.108.40.206.3.0 --> Last Change...
Thank you for your answer. Your idea sounds good, but how can I avoid a loop or spanning-tree-problems?
Given the setup:
I mirror the LAG (production LAG) to port 1 of each switch.
- Now, I connect port 1 of switch 2 to port 2 of switch 1
- ...and mirror port 2 to port 1

Now, I need to setup a monitor-port/port-mirror with an IDS-system attached to it.
Is there any possibility to mirror a MLAG?
I did not find anything about...
I need to mirror the traffic of a device, that is connected to two Arista 7050QX which are building an "MLAG-Cluster".
Do you know, if this is possible?
How can this be done?
- Mirror the Ethernet-Interface on each switch?
- Mirror with one port?
Thank you for your help!!
I decided to use different kinds of disks in Raid1/10 systems, as I have just hit a firmware-bug, where all my drives failed (and HPE has another one, today).
My "standard-disk" is currently the Intel D3-S4510 series.
Can you recommend me any other disk, that offers comparable performance...
I found this one:
RHEL: Persistent increases in RX frame and rx_brb_discard errors on 10 Gigabit network interfaces - Red Hat Customer Portal

I did an upgrade of two linux-systems. Since the update, I have exactly the same problem on both systems:
The first port of the cards shows:

I am just a bit confused on how to configure STP on a port facing to my ISP.
My fear is, that the ISP could send BPDUs and so, he could change my STP-topology.
Disable STP on that port
--> In that case: What happens, if BPDUs are received? Will they be dropped or forwarded in...
For hours now, I am trying to really understand how to configure:
- a central Linux DHCPd-server
- satellite DHCP-relays
...but I still did not reach my goal...
The main problem is:
- How does DHCPd "assign" the right subnet-zone to the relay-agent?
If the DHCPd-server owns an interface...
