NAME
gcloud compute packet-mirrorings create - create a Compute Engine packet mirroring policy
SYNOPSIS
gcloud compute packet-mirrorings create NAME --collector-ilb=COLLECTOR_ILB --network=NETWORK [--async] [--description=DESCRIPTION] [--no-enable] [--filter-cidr-ranges=[CIDR_RANGE,…]] [--filter-direction=DIRECTION] [--filter-protocols=[PROTOCOL,…]] [--mirrored-instances=[INSTANCE,…]] [--mirrored-subnets=[SUBNET,…]] [--mirrored-tags=[TAG,…]] [--region=REGION] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
Create a Compute Engine packet mirroring policy.
EXAMPLES
Mirror all tcp traffic to/from all instances in subnet my-subnet in us-central1, and send the mirrored traffic to the collector-fr Forwarding Rule. 
gcloud compute packet-mirrorings create my-pm --network my-network --region us-central1 --mirrored-subnets my-subnet --collector-ilb collector-fr --filter-protocols tcp

Mirror all traffic between instances with tag t1 and external server with IP 11.22.33.44 in us-central1, and send the mirrored traffic to the collector-fr Forwarding Rule. 

gcloud compute packet-mirrorings create my-pm --network my-network --region us-central1 --mirrored-tags t1 --collector-ilb collector-fr --filter-cidr-ranges 11.22.33.44/32
POSITIONAL ARGUMENTS
NAME
Name of the packet mirroring to create.
REQUIRED FLAGS
--collector-ilb=COLLECTOR_ILB
Forwarding rule configured as collector. This must be a regional forwarding rule (in the same region) with load balancing scheme INTERNAL and isMirroringCollector set to true. You can provide this as the full URL to the forwarding rule, partial URL, or name. For example, the following are valid values:
--network=NETWORK
Network for this packet mirroring. Only the packets in this network will be mirrored. It is mandatory that all mirrored VMs have a network interface controller (NIC) in the given network. All mirrored subnetworks should belong to the given network. You can provide this as the full URL to the network, partial URL, or name. For example, the following are valid values:
OPTIONAL FLAGS
--async
Return immediately, without waiting for the operation in progress to complete.
--description=DESCRIPTION
Optional, textual description for the packet mirroring.
--enable
Enable or disable the packet-mirroring. Enabled by default, use --no-enable to disable.
--filter-cidr-ranges=[CIDR_RANGE,…]
One or more IPv4 or IPv6 CIDR ranges that apply as filters on the source (ingress) or destination (egress) IP in the IP header. If no ranges are specified, all IPv4 traffic that matches the specified IPProtocols is mirrored. If neither cidrRanges nor IPProtocols is specified, all IPv4 traffic is mirrored. To mirror all IPv4 and IPv6 traffic, use 0.0.0.0/0,::/0
--filter-direction=DIRECTION
--filter-protocols=[PROTOCOL,…]
List of IP protocols that apply as filters for packet mirroring traffic. If unspecified, the packet mirroring applies to all traffic. PROTOCOL can be one of tcp, udp, icmp, esp, ah, ipip, sctp, or an IANA protocol number.
--mirrored-instances=[INSTANCE,…]
List of instances to be mirrored. You can provide this as the full or valid partial URL to the instance. For example, the following are valid values:
--mirrored-subnets=[SUBNET,…]
List of subnets to be mirrored. You can provide this as the full URL to the subnet, partial URL, or name. For example, the following are valid values:
--mirrored-tags=[TAG,…]
List of virtual machine instance tags to be mirrored.

To read more about configuring network tags, read this guide: https://cloud.google.com/vpc/docs/add-remove-network-tags

The virtual machines with the provided tags must live in zones contained in the same region as this packet mirroring.
--region=REGION
Region of the packet mirroring to create. Overrides the default compute/region property value for this command invocation.
GCLOUD WIDE FLAGS
