The 7705 SAR supports both copper and fiber uplinks.
Aggregate CIR for Unshaped VLANs on Network Egress Ethernet Ports
The 7705 SAR supports the configuration of one aggregate CIR rate for all the
unshaped network egress Ethernet VLANs on a port, thereby ensuring that all the
unshaped VLANs can compete with the shaped VLANs (that is, network interfaces)
at the port level for egress bandwidth. Use the config>port>ethernet>
network>egress>unshaped-if-cir command to set the aggregate CIR rate.
For more information on shaped and unshaped Ethernet VLANs, refer to the
“Per-VLAN Network Egress Shapers” and “QoS for Gen-3 Adapter Cards and
Platforms” sections in the 7705 SAR Quality of Service Guide.
3.1.3.12.4 Hybrid Ports
Hybrid ports are supported on Ethernet ports, where they provide the capabilities and
features of access and network mode ports on a per-VLAN basis. The following
services support hybrid port functionality: Epipe PW, Ipipe PW, IP-VPN, VPLS, and
IES.
For ingress traffic, QoS and traffic management on a hybrid port behaves in the same
way for access and network port modes. Refer to the 7705 SAR Quality of Service
Guide, “QoS for Hybrid Ports on Gen-2 Hardware” and “QoS for Gen-3 Adapter
Cards and Platforms” for details.
Network VLANs on a hybrid port provide OAM down MEP support, as well as port
loopback support (in line mode with latched timers only).
The following hardware supports hybrid ports:
• 6-port SAR-M Ethernet module (except for the Fast Ethernet ports (ports 1 and
2))
• 6-port Ethernet 10Gbps Adapter card
• 8-port Gigabit Ethernet Adapter card
• 10-port 1GigE/1-port 10GigE X-Adapter card (only in 10-port 1GigE mode)
• Packet Microwave Adapter card (only in Ethernet port mode (not mw-link mode))
Note: The unshaped-if-cir command does not apply to Gen-3 Ethernet adapter cards and
platforms, except for network egress in hybrid mode. In this case, the shaper-if-cir
command applies.
