Bonding and networking

Frankcheong — Mon, 20 Sep 2010 05:34:27 +0000

I am not a network guy and would like to know how can I setup the below two configurations and its pros and cons. networking component :- WAN: cisco 2970 * 1 Load balancer: F5 switch 1600 * 2 Private subnet: Cisco 2950 * 2 My situation is like that, my F5 switch 1600 will connect to Cisco 2970 upstream to the public (WAN) and all my host will connect to the pair of Cisco 2950 private lan which then interconnect to the pair of F5 switch 1600 providing load balancing as well as fault tolerance function. All of my host equip with two ethernet interface (most of them are using broadcom 5700) and they will team up and each interface will connect to one cisco switch so as to privide fault tolerate as well as link aggregation. My question is how can I config my equipements (Cisco 2970, F5 switch 1600, Cisco 2950 as well as my host) physically (cabling) and logically (system configuration?) and theirs pros and cons? 1. Host using balance-ALB. 2. Host using 802.3ad.
