Versati III has an interface that communicates via the Modbus software protocol over RS-485 (physical layer standard). RS-485 can between -7 and +12V.
This needs to be converted to TTL, Transistor-Transistor Logic, which operates at low voltages. TTL can be read by ESP32 (not RS-485)
Based on

Azure has several hierarchical levels.
From a technical perspective, the order is (highest first):
Subscription (PROD, DEV, ...).
Resource Group (grouping everything related to a service , like firewall, servers, ...)
Inside Resource Group we can have
- VMs
- interfaces
- disks
-Virtual Networks
- a VNET contains a big subnet which can then be split into smaller subnets.
- Peering between VNETs
- A routing table
- Network Security Group (Rules inbound outbound)
- NAT Gateway
- IP addresses
Installed on USB device
Has tcpdump

do :
cd /tmp
ln -s /tmp/mnt/opt opt
find /etc -type f | xargs grep "172.29.129"
which gave me
/etc/udhcpd.conf:start 172.29.129.1 #default: 192.168.0.20
/etc/udhcpd.conf:end 172.29.129.253 #default: 192.168.0.254
/etc/udhcpd.conf:opt router 172.29.129.254
so now I know that the process is called udhcpd. Then did a
systemctl restart udhcpd
and now I'm getting an IP.
Issue Cause: When vManage controls the cEdge, it change the CLI from "platform console serial" to "platform console virtual", once it changed, you lost the eve-ng console.
Following is what you need to do:
a) Create a CLI Add-On feature template, add "platform console serial" to the template
b) Associate this add-on template to the device template under the Additional Templates Section
c) Reboot your cEdge, then that fix the issue
powershell to see max MTU of win11:
netsh interface ipv4 show interfaces
ping -l 1600 <destination>
fragmented in 2 packets
first packet
ping -l 1600 -f <destination>
packet will be dropped at the laptop
To achieve this, we do vrf route leaking via static routes. It is not possible to leak directly between to vrfs, but it is possible between vrf and global in both directions.
in securecrt configure session with VT220 keyboard mapping and press F5 continuously when the router boots.
install openwrt on e4200v2
Open ssh and http on the WAN (disable firewall)
Via GUI of openwrt (LuCi) install tc-full and kmod-netem
Inject some delay:
tc qdisc add dev internet root netem delay 10ms
Disable delay:
tc qdisc del dev internet root
tc -s qdisc ls dev internet
