Enterasys Networks Security Router X-PeditionTM - Manual (Page 105)

General IP Features
XSR User’s Guide 5-3
• Troubleshooting Tools
– Ping
– Traceroute
• IP Routing
– RIP
– Triggered-on-Demand RIP updates
– OSPF including Database Overflow (RFC-1765) and Passive Interfaces
– OSPF debugging
– Static routes
– Default network
– CIDR (IP classless)
– Router ID configuration RFC-1850
– Configurable RIP and OSPF timers
– Per interface OSPF poll timer
• VLAN Routing
– Layer 3 (IPv4) forwarding of Ethernet frames with 802.1Q VLAN over FastEthernet/
GigabitEthernet interfaces
– VLAN IDs - up to 64 unique VLAN IDs per physical interface in a range from 0 to 4094
– User priority (priority bits) in a VLAN- tagged frame:
– - XSR does not prioritize traffic when forwarded
– - But priority preserved when forwarded to another VLAN port
– - Locally sourced VLAN frames and frames not accessing a VLAN interface will have
their priority bits set to 0
– Encapsulation supported over VLAN for PPPoE
– VLAN Routing supported for: OSPF, RIP, Static routes
– IP support over VLAN includes: Secondary IP addresses, NAT, Policy Based Routing
(PBR), ACLs, standard IP applications including Ping, Traceroute, Telnet, Helper
Addresses, Directed Broadcast, VPN, Firewall, DHCP Server, et al.
– VRRP and QoS supported over VLAN physical interfaces only
– QoS with VLAN supporting up to four priority queues per interface, input traffic
classification based on user priority bits in the VLAN header, and output traffic marking
by priority
– One global ARP table maintained and is shared across VLANs
– Duplicate MAC addresses not allowed across VLANs
• Policy Based Routing (PBR)
• Real Time Protocol (RTP) Header Compression
• Network Address Translation - static (NAT), Network Address Port Translation (NAPT),
dynamic NAT pool mapping with overload, PPTP/GRE ALG and arbitrary IP address for
NAPT, on the interface and port-forwarded static NAT, multiple NATs on an interface.
