|
|
QinQ VLAN
|
VLANs transparently cross a service provider network while isolating traffic among customers
|
|
Security
|
|
ACLs
|
Drop or rate limit based on source and destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag
Support up to 512 rules
|
|
Port Security
|
Creates the ability to lock source MAC addresses to ports; limits the number of learned MAC addresses
