Here’s the sample configuration for setting up the management port for different router platforms using static route. Assuming we have this IP configuration:RSP0/RE0 Physical IP : 10.10.10.98/24RSP1/RE1 Physical IP: 10.10.10.99/24 Virtual IP: 10.10.10.100/24 Gateway: 10.10.10.1/24 Note: It is advisable to connect the management plane connectivity to another network separate from data/voice network.

Objective: To separate management traffic from data/customer traffic in your Huawei Routers Preferably, Data and Management are into 2 separate network domains. Pre-requisite: UTP cables (for each MPU management port in case for switchover) are connected to a network switch to access the OOB management gateway To go configuration mode: system-view To preview configuration change before commiting display configuration candidate * * Management IP Configuration* * a. Configure the vpn instance for management ip vpn-instance <vpn instance name> description <description> ipv4-family b. Set…
Transmission Control Protocol (TCP) – is a connection-oriented communications protocol that is used to ensure reliable transmission of packets between computing devices in a network. User Datagram Protocol (UDP) – is a connection-less communications protocol that is used especially for time-sensitive and low latency transmissions across the network. Here’s a table of comparison: Parameter TCP UDP Protocol connection-oriented connection-less Header Size 20 bytes Static header 8 bytes Checksum Compulsory Optional Overhead Heavy as it needs 3 packets to setup a…
uRPF or Unicast Reverse Path Forwarding is a security feature/tool that help verifies reachability of source address in packets being forwarded. It can prevents malicious and spoofing attacks as it will perform forwarding table lookup on the source IP address. – it as defined in RFC3704 – it follows RFC2827 for ingress filtering. – it relies on the CEF (Cisco Express Forwarding) or FIB table to perform lookups. – preferably implemented at the network edge facing internet, customers and servers…

Here is an example on how to query or display optical power of an interface in a Huawei Router. This is tested using NetEngine40E Universal Service Router or NE40E running version 8.x OS. display interface <interface> extensive Sample Output: (Can see link down and not receiving any power from the neighboring device) <Huawei-NE40E>display interface GigabitEthernet1/1/1 extensive GigabitEthernet1/1/10 current state : DOWN(LOS) (ifindex: 142) Line protocol current state : DOWN Link quality grade : — Port BW: 10G, Transceiver max BW:…
Here’s a comparison table between the two network models: Open Systems Interconnect (OSI) vs Transmission Control Protocol/Internet Protocol (TCP/IP) Similarities: both are defined in layered architecture both define standards for networking both are logical models both provide framework for creation and implementation of networking standards and devices both models simplify network troubleshooting process Differences: OSI is protocol independent standard while TCP/IP model is based on standard protocols which Internet has developed OSI model is developed by International Standard Organization (ISO)…
