Hi, have few questions. Can you please answer ?
1. Why is it required to have all links of same speed, type and duplex settings to be grouped into a Etherchannel. Why not have different link speeds participate in a Etherchannel group and what are the actual effects of having different speed links in a Etherchannel. Will it have impact on performance ?
2. Can we configure STP and RSTP on the same switch ? Can we configure STP and RSTP on interface level ? And what will happen if we connect STP and RSTP switches back-to-back. What will be port states/roles on RSTP switch ?
