22 most common Cisco Catalyst switches (1)

1. How is the stacking of Catalyst 35500XL/2950XL implemented?

A. dedicated stacked cables, 1 m long or 50 cm long (CAB-GS-1M or CAB-GS- 50CM) and dedicated Gigabit stacked card GigaStack GBIC (WS-X3550-XL) (the card already contains CAB-GS- 50CM stacked cables) are required ).

B. Two stack methods can be used: the chrysanthemum Link Method (providing 1g bandwidth) or the point-to-point method (providing 2G bandwidth ).

C. Both methods can be used for backup.

D. The Chrysanthemum Link Method supports stacking of up to 9 switches, and the point-to-point method supports up to 8 switches.

2. is redundant backup supported when the Catalyst 3550 XL series switches are stacked?

There are two ways to stack the ipvst3550xl series switches: The Chrysanthemum link mode and the point-to-point mode.

When the chrysanthemum link is used, the stacked switches are connected in turn, and the transmission bandwidth between switches can reach 1 Gbps;

When using the point-to-point approach, a separate Catalyst3508G-XL switch is required,

Other switches are connected to GB by stacked GBIC cards and stacked cables, which can achieve a full duplex transmission bandwidth of up to 2 Gbps.

Both methods support stack redundancy. When you use the chrysanthemum link connection method, the redundant connection is completed by connecting the top switch with the bottom switch with a stacked cable. When a point-to-point connection is used, 2nd 3508 switches are used.

3. After a gigabit port of ipvst3550 XL is stacked with a stacked card, can another gigabit port connect to a gigabit switch or a gigabit server?

Yes.

Use 1000Base-SX GBIC or 1000Base-LX/lh gbic.

4. What network devices can be used between Ethernet Channel Tech? How to use it?

It can be used between vswitches, between vswitches and vrouters, and between vswitches and servers.

Two or four 10/100 Mbps or Mbps ports can be used by Ethernet Channel Tech ., up to 400 M (10/100 Mbps port), 4G (800 Mbps port), 10/100 M (Mbps port), 8G (Mbps port) bandwidth.

5. What is the role of Ethernet Channel Technology?

Increase bandwidth, load balancing, and line backup

6. How do I select a line when the port is set to an Ethernet Channel?

Determine the output link based on the Ethernet source address and destination address of the data frame. The Router performs or operations based on the network address to determine the output of the link.

7. What is the difference between Ethernet Channel Technology and PAgP (Port Aggregation Protocol?

PAgP is an enhanced version of the Ethernet Channel. It supports Spanning Tree Protocol and Uplink Fast on the Ethernet Channel, and supports automatic configuration of Ethernet Channel binding.

Minimum required power supply: 1 2

Packet forwarding rate 18 Mpps 18 Mpps

24 Gbps, 60 Gbps

8. Does the systst4000 series support ISL?

Supported since Supervisor Engine Software Release 5.1.

9. What is the difference between the 4008/2 and 4008/3 redundant power options of the ipvst4000 switch?

There are two power slots on the chassis of the Catalyst4003 switch. The factory comes with a power supply, and the 4008/2 is a redundant power supply customized for it. The Catalyst4006 chassis has three power slots with two power supplies at the factory, and 4008/3 is a dedicated redundant power supply customized for it.

10. Does the layer-3 Switch module of Catalyst 4006 contain Ethernet ports?

No, the layer-3 Switching Module of ipvst4006 contains 32 10/100 adaptive ports and 2 Gigabit ports. In 4003, the original WS-X4232-GB-RJ module can be replaced without affecting the network structure.

11. How to choose the two existing switch modules (product No )?

WS-X4306-GB Catalyst 4000 Gigabit Ethernet Module, 6-Ports (GBIC)

WS-X4418-GB Catalyst 4000 GE Module, Server Switching 18-Ports (GBIC)

The use environments of these two modules are different.

WS-X4306-GB is a 6-port Gigabit Switch module, each port exclusive Gigabit bandwidth, suitable for network trunk, used to connect with a gigabit interface switch; it can also be connected to a server with a gigabit Nic.

The WS-X4418-GB is an 18-port Gigabit Switching Module with two ports providing exclusive Gigabit bandwidth and the other 16 ports sharing 8 GB of Full Duplex bandwidth, but each port can burst to gigabit. This module is suitable for connecting Gigabit servers where servers are concentrated, rather than the network trunk.

12. What is the bandwidth and packet forwarding rate of the Catalyst 6000 series?

The bandwidth of the Catalyst 6500 series can be extended to 256 Gbps, and the packet forwarding rate can be extended to 150 Mpps; the Catalyst 6000 series, as a cost-effective solution, provides 32 Gbit/s of onboard bandwidth and a packet forwarding rate of 15 mpps.
