Hi @zo3
Yes, it is possible to see the exporter IP address assigned to specific interfaces in a Cisco ACI fabric. You can use the Cisco ACI API to retrieve the IP addresses assigned to each device/node in the fabric. Here are the steps to achieve this:
Using the Cisco ACI API
- Log in to the APIC:
- You need to authenticate with the APIC to get an authentication token. This token will be used in subsequent API calls.
2. Retrieve Node Information:
- Use the API to retrieve information about the nodes in the fabric, including their IP addresses.
Step-by-Step Guide
Step 1: Authenticate with the APIC
You need to send a POST request to the APIC to get an authentication token.
API Endpoint:
POST https://<APIC_IP>/api/aaaLogin.json
Request Body:
{
"aaaUser": {
"attributes": {
"name": "<username>",
"pwd": "<password>"
}
}
}
Example using curl:
curl -k -X POST https://<APIC_IP>/api/aaaLogin.json -d '{
"aaaUser": {
"attributes": {
"name": "<username>",
"pwd": "<password>"
}
}
}'
Step 2: Retrieve Node Information
Once authenticated, use the token to retrieve node information, including IP addresses.
API Endpoint:
GET https://<APIC_IP>/api/node/class/fabricNode.json
Example using curl:
curl -k -X GET https://<APIC_IP>/api/node/class/fabricNode.json -b apic-cookie.txt
Step 3: Retrieve Interface Information
To get the IP addresses assigned to specific interfaces, you can query the l3extRsPathL3OutAtt class.
API Endpoint:
GET https://<APIC_IP>/api/node/class/l3extRsPathL3OutAtt.json
Example using curl:
curl -k -X GET https://<APIC_IP>/api/node/class/l3extRsPathL3OutAtt.json -b apic-cookie.txt
Example Python Script
Here is an example Python script that uses the requests library to authenticate with the APIC and retrieve node and interface information:
import requests
import json
# APIC credentials
apic_ip = "<APIC_IP>"
username = "<username>"
password = "<password>"
# Disable warnings for self-signed certificates
requests.packages.urllib3.disable_warnings()
# Authenticate with the APIC
login_url = f"https://{apic_ip}/api/aaaLogin.json"
login_payload = {
"aaaUser": {
"attributes": {
"name": username,
"pwd": password
}
}
}
session = requests.Session()
response = session.post(login_url, json=login_payload, verify=False)
if response.status_code != 200:
print("Failed to authenticate with APIC")
exit(1)
# Retrieve node information
nodes_url = f"https://{apic_ip}/api/node/class/fabricNode.json"
response = session.get(nodes_url, verify=False)
nodes = response.json()["imdata"]
# Print node information
for node in nodes:
node_attrs = node["fabricNode"]["attributes"]
print(f"Node ID: {node_attrs['id']}, Name: {node_attrs['name']}, IP: {node_attrs['address']}")
# Retrieve interface information
interfaces_url = f"https://{apic_ip}/api/node/class/l3extRsPathL3OutAtt.json"
response = session.get(interfaces_url, verify=False)
interfaces = response.json()["imdata"]
# Print interface information
for interface in interfaces:
interface_attrs = interface["l3extRsPathL3OutAtt"]["attributes"]
print(f"Interface: {interface_attrs['tDn']}, IP: {interface_attrs['addr']}")
# Close the session
session.close()
