Cisco routers are widely used in network interconnection, among which the 2500 series routers are used in a large number of low-end users. So what if you accidentally forget the Super User password for the 2500-series Router?

When talking about the Unified Communication field, we are sure we know the contest between Cisco and Microsoft. From their own development perspective, Cisco = hardware, Microsoft = software. So two completely different methods bring different solution concepts to enterprises. What are their characteristics? Cisco and

There are many things worth learning about in the PPP protocol. Here we will focus on the content of PPP frame relay. First, let's take a look at the basic concepts. PPP: Point-to-Point Protocol. Huawei routers are encapsulated by default and are character-oriented control protocols. HDLC: Advanced Data Link Control Protocol. It is a bit-Oriented Control Protocol and is the default encapsulation of
