www.h3c.com 18

Port Features Precautions

Broadcast storm suppression In the port mode, the suppression percentage of the 64-byte broadcast/multicast/unknown unicast packet is

accurate. This is because that the chip supports broadcast suppression based on PPS only. In the case of percentage-based suppression, the system converts the percentage into PPS based on 64 bytes. Therefore the PPS mode is recommended.

Broadcast/Multicast/Unknown unicast suppression does not change the port’s instantaneous speed, but prohibits packet forwarding in a certain period to implement suppression.

When broadcast/multicast/unknown unicast suppression and CAR are concurrently enabled on a port, the final wire speed is calculated with the following formula: CIR/wire speed * packets suppression pps.

Port aggregation The selected/unselected principles of V3/V5 static aggregation ports are different. When there are over

eight ports to be aggregated, products at the two ends may select different ports. IP unicast packet: load balancing based on source/destination IP and source port Non-IP unicast packet: load balancing based on source/destination MAC, VLAN and ethertype IPMC multicast: load balancing based on source/destination IP and incoming port index Other multicast/broadcast/unknown unicast packet: load balancing based on source/destination MAC and

incoming port index

www.h3c.com 21

Selective QinQ S5500-SI serves as the PE:

In the uplink direction, the UNI port processes a received packet as follows: 1) Search the mapping table of inner VLANs and

outer VLANs configured by the user for S-VLAN based on incoming port number and C-TAG;

2) Search the MAC table for outgoing port based on S-VID and C-DA;

3) Learn MAC address based on S-VID and C-SA; 4) Insert S-TAG into the packet, and then send it out

through the outgoing port; 5) For the untagged or Pri-tagged packet, insert VID

(equal to PVID of port) TAG into the packet, and then send it out.

In the downlink direction, the UNI port processes a packet as follows: 1) Search the MAC table for outgoing port based on

S-VID and C-DA; 2) Learn MAC address based on S-VID and C-SA; 3) Strip off S-TAG, and then send the packet out

through the outgoing port.

Multicast Precautions

IGMP SnoopingWhen IGMP Snooping is enabled in a VLAN, uplink

multicast data will flood the VLAN if no member joins in any multicast group. The solution is to enable unknown multicast discard in the VLAN.

Note: When unknown multicast discard or multicast port source discard is enabled in the VLAN, multicast packets (such as OSPF, RIP and NTP) will be discarded.

Multicast VLAN +Support multicast VLAN duplication, and port duplication

capability is 64. The whole system shares 1K entries, and supports duplication of maximum of 16 ports in full configuration in the case that every port joins in 128 groups.

Common Fault Location——DIAG Mode

The S5500-SI integrates the diagnosis mode provided by the chip manufacturer, enables the user to view hardware entries in the chip in real time, and realizes the convenient on-line diagnosis function. The operation steps are as follows: Type diag in any view, and the system displays a prompt

whether to enter the diag mode. Type Y and password sdk to enter the diag mode.

Choose the chip number to view. Type the command to view the desired entry. The user can

type ? or help to display all the available commands.____________________________

Common Fault Location——QACL Realization

QACL realization – hardware resourcesThere are four TCAMs in the chip. Each TCAM contains

128 entries. TCAMs are numbered 0, 2, 4 and 6, and entries in each TCAM are numbered 0 to 127. Every entry corresponds to a rule of the user, and is numbered TCAM_id * 128 + entry_id.

Common Fault Location——QACL Realization

QACL realization - priorityWhen viewing a rule, the user can see its global number,

work out TCAM_id and entry_id based on the number, and then figure out its position in the chip.

Priority relations among rules are as follows: In different TCAMs, the larger TCAM_id is, the higher

priority is; while the smaller entry_id is, the higher priority is. TCAM0 is reserved by the system, and unavailable for

users.
