SSO is compatible with the following list of features. However, the protocol database for these features
is not synchronized between the standby and active supervisor engines:
• 802.1Q tunneling with Layer 2 Protocol Tunneling (L2PT)
• Baby giants
• Jumbo frame support
• CDP
• Flood blocking
• UDLD
• SPAN/RSPAN
• NetFlow
The following features are learned on the standby supervisor engine if the SSO feature is enabled:
• All Layer 3 protocols on Catalyst 4500 series switches (Switch Virtual Interfaces)
