18 Force10 Resilient Ring Protocol (FRRP) Overview Force10 Resilient Ring Protocol (FRRP) is supported on Dell Force10 platforms, as indicated by the characters that appear under each of the command headings: e E-Series, c C-Series, s S-Series, , or . FRRP is a proprietary protocol for that offers fast convergence in a Layer 2 network without having to run the Spanning Tree Protocol. The Resilient Ring Protocol is an efficient protocol that transmits a high-speed token across a ring to verify the link status. All the intelligence is contained in the master node with practically no intelligence required of the transit mode. Commands The FRRP commands are: • clear frrp • debug frrp • description • disable • interface • member-vlan • mode • protocol frrp • show frrp • timer Important Points to Remember • FRRP is media- and speed-independent. • FRRP is a Dell Force10 proprietary protocol that does not interoperate with any other vendor. • Spanning Tree must be disabled on both primary and secondary interfaces before Resilient Ring protocol is enabled.
