Naming Conventions of Huawei S5300 switch

QQ图片20170623143149

A: Switch

B: 6: 10GE downlink ports
5: GE downlink ports
3: Layer 3 switch with 100M downlink ports
2: Layer 2 switch with 100M downlink ports

C: 3: Switch applied to carrier networks

D: Product sub-series (such as 00 or 10)

E: Maximum number of ports
NOTE
On an S5310-EI switch (such as S5310-28C-EI, S5310-52C-EI), this field indicates the number of fixed
ports on the switch.

F: Uplink port type:
C: The product supports extended cards and its uplink ports are provided by an extended card or are fixed 10GE ports.
PC: The product supports extended cards and its uplink ports are provided by an extended card or are fixed GE ports.
X: The product has fixed 10GE uplink ports.
TP: The uplink ports of the product include combo ports consisting of electrical and optical ports.
P: The uplink ports of the product are fixed GE optical ports.
NOTE
If the product name does not contain this field, the switch has no uplink port.

G: Power over Ethernet (PoE) model
NOTE
If the product name does not contain this field, the switch does not support PoE.

H: Device type
LI: lightweight version
SI: standard version
EI: enhanced version
HI: high-level version, which supports high-performance operation, administration, and maintenance (OAM) and built-in real-time clock (RTC)

I: Downlink port type:
24S: 24 downlink SFP optical ports
48CS: 48 downlink compact SFP (CSFP) optical ports
NOTE
If the product name does not contain this field, all downlink ports of the switch are electrical ports.

J: Powering mode:
AC: switch using alternating current power supply
DC: switch using direct current power supply
BAT: battery LAN switch
NOTE
Some product models that support pluggable power modules are sold with AC or DC power modules (standard configuration), and their product names contain “-AC” or “-DC”.
However, the silkscreen or nameplate on the chassis does not contain “-AC” or “-DC”.
For example, the S5320-56C-EI supports pluggable AC and DC power modules. If its
standard configuration includes AC power modules, its product name is S5320-56C-EI-
AC, but the name on its silkscreen or nameplate is still S5320-56C-EI.

Port Numbering Conventions

Physical ports are numbered in the following way:
A single switch uses slot ID/subcard ID/port sequence number to identify physical ports.
Slot ID: indicates the slot where the switch is located. The value is 0.
Subcard ID: indicates the ID of a subcard.
Port sequence number: indicates the sequence number of a port on the switch.
A stacked switch uses Stack ID/subcard ID/port sequence number to identify physical ports.
Stack ID: indicates the ID of a stacked switch. The value ranges from 0 to 8.
Subcard ID: indicates the ID of a subcard.
Port sequence number: indicates the sequence number of a port on the switch.

Statistic show only input packets. PVST+ packets cannot be transmitted properly.

Handling Process

By default, on V200R003 version, the packets with destination MAC address 0100-0ccc-cccc are processed as BPDUs, and packets with destination MAC address 0100-0ccc-cccd are forwarded by the hardware as data.

Because are forward as data packets, it will not be transmitted over layer 2 protocol tunnel. In this case we need to enforce the switch to process DA 0100-0ccc-cccd packets as bpdu and not as data packets.

Configuration:

<HUAWEI> system-view
[HUAWEI] bpdu mac-address 0100-0ccc-cccd

Root Cause

Capturing the packets on Gi0/0/3, relieved that packets are send through the tunnel without changing the destination address.

QQ图片20170621141938

Since in the switch configuration we add  “l2protocol-tunnel pvst+ group-mac 0100-0ccd-cdd0” command for l2protocol-tunnel group-mac definition, packets entering to the tunnel should have destination address, changed from “0100-0ccc-cccd” (default value) to “0100-0ccd-cdd0”.

Suggestions

Bridge protocol packets belonging to devices from other vendors need to be processed as BPDUs. You can set the MAC address of such packets to the MAC address of BPDUs

Handling Process

  1. Check Tecal server product documentation. See that management port support only 100Mb rate.
    2. Check S9703 line card.
    It is EH1D2X40SFC0, has  forty 10GE BASE-X optical ports.
    3. From dis transceiver command we see, that  1000_BASE_T_SFP is used.
    4. Tried to use command speed 100 at XGE interface of S9703 switch. No such command at interface.

    [DC-Core-XGigabitEthernet1/0/6]  undo negotiation auto
    Speed 100
    Error: Unrecognized command found at ‘^’ position.

    5. Check S9703 documentation about speed command. See NOTE.

Root Cause

NOTE:
When an XGE interface has a GE copper module installed, the rate of the interface can only be negotiated to 1000 Mbit/s.

Unable to check packet remarking when doing local port mirroring

Issue Description

After i configure dscp remarking on S5700 for all inbound ip traffic, i was not able to check if the new dscp value was written in the IP header DSCP field, using simple port mirroring.

Remarking policy:

[S9303_29_205-GigabitEthernet2/0/11]port-mirroring to observe-port 1 outbound

Result: on outbound, captured packet didn’t have dscp value changed to af41.

Alarm Information

none.

Handling Process

How port mirroring works? Basically copy the packets and sent them out towards monitoring device. What if packets are copy before being processed by QoS module?

So after researching about how switch chipset works, i found out that mirroring software module for egress packet flow is located before QoS module in the CHIP architechture and packets are copy before being affected by any qos action.

To confirm this, i have captured packets on remote end inbound, and here packets were marked properly with AF41.

Root Cause

none.

Suggestions

none.

MA5800 Product overview

The MA5800 is the industry’s first smart aggregation OLT with a
distributed architecture. It is positioned as the next-generation OLT for
NG-PON. The product is designed to help carriers build networks with
larger bandwidths, higher speeds, and smarter connectivity to deliver
better service experience.
 Providing GPON, 10G GPON, P2P GE, and 10GE access, the MA5800
supports deployment on FTTH, FTTD, FTTB, FTTC, and distributed
converged cable access platform (D-CCAP) networks. This makes it
applicable to home access, enterprise access, mobile backhaul, and
Wi-Fi hotspot backhaul scenarios to aggregate all services on one fiber
network.
The MA5800 functions as a large-capacity aggregation device on the
network to aggregate the traffic from ONTs, MDUs, and campus
switches, thereby simplifying the network architecture and reducing the
OPEX.
