Parameters With Ioc Card Redundancy - Symmetricom TimeProvider 5000 User Manual

Parameters
with IOC Card Redundancy
Both of the redundant IOC cards share the same configuration, IOC1, so both IOC
cards will have the same IP addresses and Clock IDs for the Ethernet ports on
either card. Each PTP port on each IOC card has a unique MAC address, but it may
not be used in the port redundancy mode.
IP Addresses and MAC Addresses with Independent Ports
The IP address for the ETH1 port will be the same for IOC1 and IOC2, as shown in
Figure D-2.
The IP address for the ETH2 port will be the same for IOC1 and IOC2.
Each port on each IOC card will retain a unique MAC address, regardless of IOC
redundancy. See
IP Addresses and MAC Addresses with Port Redundancy
If Port Redundancy (Bonding) is enabled, interface bond0 will be added on both
redundant IOCs. ETH1 and ETH2 will become the slave interface of bond0.
Interface bond0 will use the ETH1 MAC address and ETH1 IP address. As slave
interfaces, ETH1 and ETH2 will not carry an IP address. ETH1 will use its own MAC
address, while ETH2 will use the ETH1 MAC address. The redundant IOC bond0
interface will have the same IP address as the active IOC. However, the MAC
addresses of bond0, ETH1, and ETH2 will use the MAC address of ETH1 of its own
card. See Figure
Note:
assign the IP addresses for ETH1 and ETH2 to different subnets.
Clock IDs
Clock IDs normally self-generate for IOC ports using the MAC-based method
described in IEEE-1588. Essentially, the Clock ID is generated by inserting the two
bytes "FFFE" between the first 3 bytes and last 3 bytes of the MAC. For example, a
MAC of "00:b0:ae:01:90:ea" will have a Clock ID of "00:b0:ae:ff:fe:01:90:ea". In
non-port-redundant mode, the independent ETH1 and ETH2 ports of an IOC use
the Clock IDs associated with their individual MAC addresses. See
