Hi,

I hope some one can help with this.

I currently have 2 Cisco switches connected together and i want to plug my HP Server into to allow for redundancy in case one switch or NIC fails.
The server has 4 NIC's installed
I would also like to (if possible) have 2 NICs plugged into 1 switch and 2 in the other and etherchannel these to increase the Network speed of the server.

What would be the best way of doing this?

Thanks

James

Hi,

It is good idea!

- You  use etherchannel or PAgp
- Yuou must use spanning-tree top prevent loops!

Manageability is also included among the many features of Fast EtherChannel. It can easily be configured using the Command Line Interface or by SNMP management applications such as CiscoWorks.

Cisco Works for Switched Internetworks will graphically display Fast EtherChannels between devices as well as collect statistics for both individual Fast Ethernet links within the channel and aggregate statistics for the Fast EtherChannel.

Another integral management benefit of Fast EtherChannel is the ability to detect, report, and prevent the use of incorrectly paired interfaces within the channel. Consistency checks are completed before activation of a channel to ensure network integrity.

A key enabler of these capabilities is PAgP, which aids in the automatic creation of Fast EtherChannel links. Upon power-on or reconnection, a port sends PAgP packets between Fast EtherChannel-capable ports. Neighboring devices learn of each other's port capabilities and their ability to form channels.

After the protocol determines correctly paired, bidirectional, point-to-point links, it groups the ports based on device hardware, software, and user-configured capabilities into a channel.

With PAgP implemented both in the network and on mission-critical servers, Fast EtherChannel bundles can be automatically discovered and configured with transparent ease.

Benefits summary

Fast EtherChannel is a technology-leveraging, standards-based Fast Ethernet used in parallel to provide the additional bandwidth networks require today. It is readily adaptable in the future to provide Gigabit EtherChannel as Gigabit Ethernet standardization is completed.

In the interim, it provides flexible, scalable bandwidth with resiliency and load sharing across links for switches, router interfaces, and servers. Fast EtherChannel provides the tools for network managers to build high-speed solutions today for their mission-critical networks, while leveraging their existing cabling and network device infrastructure.

Further, with Fast EtherChannel's PAgP, Cisco and HP, through its Auto-Port Aggregation software, are the first to offer automatic discovery and configuration manageability benefits to Fast Ethernet users. These capabilities also lead to lower total cost of ownership benefits. Fast EtherChannel's resiliency is further capitalized when used with HP's MC/ServiceGuard facilities to satisfy today's requirements for high availability networks.

Increased performance, scalability, manageability, and availability are among a few of the many benefits Cisco and HP deliver to their customers in providing end-to-end Enterprise solutions.
