Technical Tip: Mapping Port Counters on NP7 Hardware Platforms

[aionescu]

Description	This article explains how to correlate port counters with the various components of FortiGate NP7-based platforms.
Scope	NP7 Hardware Platforms.
Solution	The 'diagnose hardware deviceinfo nic <port_number>' command in FortiOS displays port information, including descriptions, link status, and counters. When executed on a port connected to the integrated switch fabric on an NP7 platform, these counters are sourced from multiple components. The following is a typical set of information recorded on a FortiGate-3501F running v7.4.8 and collected on port1 using the following command: diagnose hardware deviceinfo nic port1 Output Description Description: FortiASIC NP7 Adapter NPU driver name pid: 0 A unique id for specific configuration oid: 128 FortiGate Object Identifiers (OID) for this interface vid: 2 Interface vlan id macid: 0 macid is used by Fortigate to search for MAC address from MAC table eif_id: 127 Ethernet interface id on NP7 promiscous: 0 If the interface is in promiscuous mode vlan_wa_done: 0 vlan workaround flag mtu: 1500 Interface MTU size netdev oid: 128 FortiGate Object Identifiers for network device dev-flags: 1102 A special flag indicates certain feature is turned on/off dev-promis: 1 Network device promiscuous mode flag Current_HWaddr: 00:09:0f:09:00:00 Network device current MAC address Permanent_HWaddr: 80:80:2c:2c:fe:54 Interface’s permanent MAC address Default Link Settings: Output Description auto-nego: Disable Default auto negotiation enable/disable s_speed: 10000 Default port speed s_duplex: Full Default port duplex Current Link Settings: Output Description auto-nego: Disable Current auto negotiation enable/disable s_status: Down Current link status up/down s_speed: 10000 Current port speed s_duplex: Full Current port duplex FEC: OFF (0x2) Forward Error Correction (FEC) feature on/off FEC_cap: CL91,CL74 (0x18) Supported Forward Error Correction (FEC) features SerDes_if: SR SerDes (Serializer/Deserializer) interface type SerDes_if_cap: GMII,SGMII,SR,LR,CR (0x3e) Supported SerDes (Serializer/Deserializer) interface type SerDes_dflt: 3 Default SerDes configuration or profile pm_mode_setting: 1 Port module mode setting pm_mode: 0x6 Port module current mode pm_mode_dflt: 1 Port module default mode pm_port: Yes The interface belongs to a port group (port module) medium_mode: 0 Port medium type (copper or fiber) Link Status: Output Description Admin: Down Desired state set by the administrator link_status: Down State of a physical network connection, whether it's active (up) or inactive (down) Speed: N/A Speed of a network port Duplex: N/A Specifies how data is transmitted and received on the link Netdev Status: Output Description dev_running: No The state of the network device, the link is established or not dev_carrier: Off The network device's carrier state Host Counters: Output Description hrx_pkts: 0 Total host RX packet count hrx_bytes: 0 Total host RX byte count htx_pkts: 0 Total host TX packet count htx_bytes: 0 Total host TX byte count htx_drop: 0 Total host TX drop count htx_e_busy: 0 Total host TX busy error count htx_e_noheadroom: 0 Total host TX no head room error count htx_e_oid: 0 Total host TX oid error count htx_e_adapter: 0 Total host TX adapter error count htx_e_pad: 0 Total host TX pad error count htx_e_frag: 0 Total host TX fragment error count htx_e_other: 0 Total host TX unknown error count Netdev Counters: Output Description Rx Pkts: 0 Network device total RX packet count Rx Bytes: 0 Network device total RX byte count Tx Pkts: 0 Network device total TX packet count Tx Bytes: 0 Network device total TX byte count Switch Poll Counters: Output Description sw_tx_pkts: 0 Total TX packets from switch counter sw_tx_bytes: 0 Total TX bytes from switch counter sw_tx_bc_pkts: 0 Total TX broadcast packets from switch counter sw_tx_mc_pkts: 0 Total TX multicast packets from switch counter sw_rx_pkts: 0 Total RX packets from switch counter sw_rx_bytes: 0 Total RX bytes from switch counter sw_rx_bc_bytes: 0 Total RX broadcast packets from switch counter sw_rx_mc_bytes: 0 Total RX multicast packets from switch counter Switch Error Counters: Output Description rx_err: 0 Total RX errors from switch counter rx_crc_err: 0 Total RX CRC errors from switch counter rx_len_err: 0 Total RX length errors from switch counter rx_carrier_err: 0 Total RX carrier errors from switch counter rx_over_err: 0 Number of jumbo frame (>1500) received rx_under_err: 0 Undersized packet on Rx (< 64 bytes) rx_drop_pkts: 0 Number of dropped packets on Rx tx_collision_err Total TX collision errors from switch counter tx_drop_pkts: 0 Number of dropped packets on Tx Transceiver Info: Output Description tx_disable: N/A Transceiver’s transmitter output is turned off/on rx_los: N/A Indicates the transceiver is not attached or cable is disconnected tx_fault: N/A Indicates a problem with the transmit side of the transceiver present: N/A Transceiver is attached or plugged in last_spd: 0 Last recorded or negotiated speed of the transceiver Note: The diagnose hardware deviceinfo nic <port_number> command's output (specifically the counter list) can vary slightly between FortiOS releases. However, the organization and categorization of those counters remain consistent across different versions.
