Field Documentation

◆ dstAddr

uint8_t CpswMacPort_InterVlanRoutingCfg::dstAddr[ENET_MAC_ADDR_LEN]

Destination address

◆ srcAddr

uint8_t CpswMacPort_InterVlanRoutingCfg::srcAddr[ENET_MAC_ADDR_LEN]

Source address

◆ vlanId

uint32_t CpswMacPort_InterVlanRoutingCfg::vlanId

VLAN Id

◆ replaceDASA

bool CpswMacPort_InterVlanRoutingCfg::replaceDASA

Whether routed packet's destination address will be replaced with dstAddr and packet's source address will be replaced with srcAddr

◆ forceUntaggedEgress

bool CpswMacPort_InterVlanRoutingCfg::forceUntaggedEgress

Destination VLAN Force Untagged Egress. When set, this bit indicates that the VLAN should be removed on egress for the routed packet.

◆ decrementTTL

bool CpswMacPort_InterVlanRoutingCfg::decrementTTL

Decrement Time To Live. When set, the Time To Live (TTL) field in the header is decremented:

  • IPV4 - Decrement the TTL byte and update the Header Checksum
  • IPV6 - Decrement the Hop Limit

Note: When this bit is set, the ALE should be configured to send any IPv4/6 packet with a zero or one TTL field to the host. When this bit is cleared the TTL/Hop Limit fields are not checked or modified.
