![]() ![]() MAC ACL is only used for non-IP packets such as ARP. Interfaces (Layer 2 switch port, Layer 3 routed port). MAC filter won't capture IP packets even if it matches the MAC address. You can define up to eight capture points, but only one can be active at a time. Use filters to limitĭNA Advantage supports decoding of protocols such as Control and Provisioning of Won't be captured on an interface egress capture.Ĭontrol plane packets aren't rate limited and performance impacting. The Rewrite information of both ingress and egress packets aren't captured.ĬPU-injected packets are considered control plane packets. It's not possible to modify a capture point parameter when a capture is already active orĮPC captures multicast packets only on ingress and doesn't capture the replicated packets on This includes TTL, VLAN tag, CoS, checksum, MACĮven though the minimum configurable duration for packet capture is 1 second, packet capture works for a minimum of 2 seconds. Packets captured in the output direction of an interface might not reflect the changes madeīy the device rewrite. ![]() Way, you must delete the capture point and create a new one, once the If you change interface from switch port to routed port (Layer 2 to Layer 3) or the opposite It'sĪ VLAN interface that is in shutdown state doesn't support EPC. You can't use VRFs, management ports, and private VLANs as attachment points.Įmbedded Packet Capture (EPC) isn't supported on logical ports, which includes portĬhannels, switch virtual interfaces (SVIs), and subinterfaces. Restrictions for Configuring Embedded Packet Capture Packet length range as a filter can’t be used in addition with any other filters. Packet length range as a filter for packet capture isn’t supported for non- IPv4/IPv6 Using the term len 0 command) may make the console or terminal unusable. The output format is different from previous releases.Ī Wireshark session with either a longer duration limit or no capture duration (using a terminal with no auto-more support Not NVGEN’d and aren’t synchronized to the standby Supervisor in NSF and SSOĮmbedded Wireshark is supported with the following limitations:Ĭapture filters and display filters aren't supported. The CLI for configuring Wireshark requires that the feature is executed only from EXEC mode.Īctions that usually occur in configuration submode (such as definingĬapture points), are handled at the EXEC mode instead. The coreįilter is based on the outer CAPWAP header. The same behavior occurs if weĬapture a Layer 2 interface carrying DTLS-encrypted CAPWAP traffic. If youĬapture a DTLS-encrypted CAPWAP interface, two copies are sent to Wireshark, If you capture both PACL and RACL on the same port, only one copy is sent to the CPU. Otherwise, Wireshark traffic will be contaminated We recommended that you deactivate ACL loggingīefore starting Wireshark. Once you activate Wireshark, it takes priority.Īll traffic, including that captured by ACL logging on any ports, is Wireshark doesn't capture packets dropped by floodblock.Ī Wireshark class map allows only one ACL (IPv4, IPv6, or MAC).ĪCL logging and Wireshark are incompatible. You can't change a capture point when the capture is active. You can start only one session when using high-speed When the matching traffic rate exceeds this number, you mayĮxperience packet loss. With high-speed capture supports roughly 750Mbps (measure with 256-byte The lock-step mode supportsĪpproximately 45 Mbps (measured with 256-byte packets). The streaming capture mode supports approximately 1500 pps. ![]() With an attachment point is unplugged from the device. For example, if the device that is associated Wireshark stops capturing when one of the attachment points (interfaces) attached to aĬapture point stops working. Wireshark can't capture packets on a destination SPAN port. You need to restart theįile limit is limited to the size of the flash in DNA Advantage. If you delete the file used by an active capture session, the capture session can't createĪ new file. Wireshark doesn't support limiting circular file storage by file size. Wireshark doesn't support Global packet capture. ![]()
