Although both Telnet and SSH can provide remote control, I recommend that you use SSH, as SSH encrypts the traffic. Web interfaces are not commonly used, but for non-technical users, there is some information that can be easily viewed through the web interface.In a traditional switch environment, we are told time and time again to restrict configuration management traffic to a dedicated VLAN. This approach does a good job of separating management traffic from data traffic, provides some security, and also enables fault isolation. So it is no surprise that the Nexus appliance platform has inherited this concept as well, both physically separating management ports from data ports and logically separating traffic between the two.Speaking of separation ...... management ports have their own IP addresses, subnet masks, and even use their own routing tables! We use a technique called virtual routing and forwarding to isolate the routing tables of the management ports, or VRF for short, a technique that allows us to have multiple separate routing tables on the same device. VRFs are discussed in detail later in this chapter.Okay, now take a minute to review the Nexus 5010 photo shown in Figure 7.4. Do you know why there are two management ports here? I hope you've already asked that question! We normally use management port 0, management port 1 is not normally used, it is a 1Gbit/s Ethernet port. That means we can connect this port with an RJ45 category 6 cable, connect it to the management port of another Nuxus switch and use this port for transmission and only for management traffic.Never forget that you must use the Console port to configure the IP information for the management port, and after that is configuredAfter that, you can only manage this device by remote means.7.1.4 L1/L2 portsI guess you probably noticed the L1/L2 ports in the Nexus 5010 photo, but what do you think they do? According to Cisco's official explanation, these ports are not available and they are currently disabled. As I said before, I won't be covering the different models separately in this chapter, but the above explanation sometimes doesn't hold true. At the time of this writing, the L1/L2 ports on the Nexus 5000 series switches are indeed in a disabled state, but this may not be the case for other models.The Cisco UCS Matrix Interconnect devices look very similar to the Nexus 5000 series switches and at first glance many people get confused, but they work in pairs and use L1 and L2 ports to communicate management information between devices - isn't that great!197
