- Unicast MAC address filtering to drop packets with specific source or destination MAC addresses (available only with the EI)
- The switch supports up to 4094 VLAN IDs to allow service provider networks to support the number of VLANs allowed by the IEEE 802.1Q standard (available only with the EI)
- DHCP snooping to filter untrusted DHCP messages between untrusted hosts and DHCP servers (available only with the EI)
- Standard and extended IP access control lists (ACLs) for defining security policies (available only with the EI)
- Automatic QoS (auto-QoS) to simplify the deployment of existing QoS features by classifying traffic and configuring egress queues (only available in the EI)
- IP Differentiated Services Code Point (IP DSCP) and (CoS) marking priorities on a per-port basis for protecting the performance of mission-critical applications (only available with the EI)
- Flow-based packet classification (classification based on information in the MAC, IP, and TCP/UDP headers) for high-performance quality of service at the network edge, allowing for differentiated service levels for different types of network traffic and for prioritizing mission-critical traffic in the network (only available in the EI)
- Policing is available only in the EI.
- RSPAN is available only in the EI.
2950 roznice SI/EI /IOS: 12.1(22)EA2/
niedługo będę zavzynał switching, wiec przygladam się watkom o przełącznikach...
prubuję przede wszytskim dociec jaka wersje softu mam na swoim 2950...
i tak....
- access-listy moge robić, czyli wskazuje ze mam EI
No i jaka wkoncu mam wersje?

- access-listy moge robić, czyli wskazuje ze mam EI
- VLAN's ID mam 1009 wiec by sugerowało ze to nie EI.- Standard and extended IP access control lists (ACLs) for defining security policies (available only with the EI)
No i jaka wkoncu mam wersje?
Re: 2950 roznice SI/EI /IOS: 12.1(22)EA2/
To jest fajny feature. Ale radzę go używać w wersji co najmniej 12.1(22)EA3 bo mogą się przytrafić niemiłe niespodziankimarcins pisze: - DHCP snooping to filter untrusted DHCP messages between untrusted hosts and DHCP servers (available only with the EI)
