ME Switches<\/span><\/p>\n

– Metro Ethernet<\/p>\n

\u00a0– All ports are shutdown by default<\/p>\n

\u00a0 \u00a0 \u00a0-> Except uplink ports<\/p>\n

\u00a0– Ports<\/p>\n

\u00a0 \u00a0 \u00a0-> Downstream<\/p>\n

\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 -> Going towards the client<\/p>\n

\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 -> User Network Interface (UNI)<\/p>\n

\u00a0 \u00a0 \u00a0-> Upstream<\/p>\n

\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 -> Going towards \u00a0SP core<\/p>\n

\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 -> Network Node Interface (NNI)<\/p>\n

\u00a0 \u00a0 \u00a0-> Downstream ports are isolated by default<\/p>\n

\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 -> Can’t communicate with each other<\/p>\n

\u00a0 \u00a0 \u00a0-> Downstream ports can communicate with upstream ports by default<\/p>\n

UNI <–> NNI<\/p>\n

UNI <-\/-> UNI<\/p>\n

On UNI ports, processing of these protocols is disabled<\/p>\n

\u00a0– STP<\/p>\n

\u00a0– CDP<\/p>\n

\u00a0– LLDP<\/p>\n

If a client wants STP \/ CDP \/ LLDP \/ etherchannel to be activated on downstream ports, the ports must be changed<\/p>\n

\u00a0– Enhanced Network Interface (ENI)<\/p>\n

No DTP<\/p>\n

\u00a0– Trunk and access are the only options<\/p>\n

Only dot1q is supported<\/p>\n

No VTP support<\/p>\n

Default interface configuration is “static access”<\/p>\n

To change the port type<\/p>\n

int fa0\/1<\/span><\/p>\n

\u00a0port-type { uni | eni | nni }<\/span><\/p>\n

sh port-type<\/span><\/p>\n

All VLANs on UNI ports are “uni-isolated” type<\/p>\n

\u00a0– To enable communication between UNI ports, change the VLAN type to “uni-community”<\/p>\n

int range fa0\/1 – 5<\/span><\/p>\n
