8 ports as core switch is OK; core switches should have higher port speeds then access one. but you should use EtherChannels links between access to distribution/core switches. so, 2 links between switches. if your 8 port switch does not have enough ports, then use regular 3660 L3 switches (assuming access switches are 2960 or 2950s.

I can add to what they have said already that switches usually always start with /1 whereas routers always start with /0. So for a two port router you might find g0/0 and g0/1 and for a 24 port switch you will normally see fa0/1 through to fa0/24. To see all the ports on a router or switch you just need to run the command show ip interface brief.

Yes, most new Cisco switches (2950, 2960, 3550, 3560, 3570) have a 32Gbps switching backplane, and the 24-port 10/100/1000 Mbps versions of these popular switches can handle this load with no problem. The 48-port versions will not (48Gbps all ports vs 32Gbps backplane). The Cisco 6500 series can have switching backplanes as high as 720 Gbps.

I'm a bit confuse w/ combo ports. So just to clarify, this switch has 24 ports 100 mbps for downlink and 2 x 1gig SFP combo ports. So lets say i connect a copper cable on PORT # 1 on the standard port (the one on the 24 ports) and use Fiber optic transceiver on …

2024年4月5日 · I was trying to demonstrate how to do initial cisco switch configuration using a console cable to connect a 2960 switch to my laptop's USB port. The cable I used has a UART to USB adaptor which I used to connect to my laptop, but I could not connect to the switch to access the CLI of the device. What could be the problem and what do you suggest?

This is now the default switch port mode for all. Ethernet interfaces on all new Cisco switches. switchport mode trunk Puts the interface into permanent trunking mode and negotiates. to convert the neighboring link into a trunk link. The interface becomes a trunk interface. even if the neighboring interface isn’t a trunk interface.

2021年2月16日 · so if i want to send information internally from switch port 1 to switch port 5 .. and another port (switchport 7) also wants to send information out switchport 5 then ...they can both send to switchport 5 at the same time and all information is buffered and prevented from colliding by the switches CPU and internal memory.

8 total switch ports = 8 collision domains. 3 separate L2 VLANs on each switch, (1, 10, 20) means that there are a total of 6 separate L2 broadcast domains. Vlans 10 and 20 on SW1 is 2 L2 broadcast. Vlans 10,and 20 on SW2 is another L2 broadcast.

2022年6月2日 · The possibility of loops occurs when you "lie" to the switch and connect another switch on a portfast'd interface. In other words, if it wasn't for portfast, bpduguard wouldn't be necessary at all. b) NO. bpduguard doesn't transition the …

A Routed port is a physical port on a switch, that acts like a port on a router. It supports all routing protocols. It does not however support VLAN subinterfaces and it is also not associated with a single VLAN. It is configured on a port connected to a router.
